Source of income: from dividends vs sale of principal or security
The trend in ETFs is total return: where the ETF automatically reinvests dividends.  This philosophy is undoubtedly influenced by that trend. The rich and retired receive nearly all income from interest, dividends, and capital gains; therefore, one who receives income exclusively from dividends and capital gains must fund by withdrawing dividends and/or liquidating holdings. For a total return ETF, the situation is even more limiting: income can only be funded by liquidation. The expected profit is lost for the dividend as well as liquidating since the dividend can merely be converted back into securities new or pre-existing.  In this regard, dividends and investments are equal. One who withdraws dividends and liquidates holdings should be careful not to liquidate faster than the rate of growth. "Some people have this notion that withdrawing dividends from savings   is somehow okay but withdrawing principal is not.  Note, this notion. Would someone please explain the ""mistake"" on P214 and why it's a   mistake? Because there may be times where withdrawing principal may be a good idea as one could sell off something that has gained enough that in re-balancing the portfolio there are capital gains that could be used for withdrawing in retirement. How and why does the sale of financial instrument equate to the   receipt of dividends?  In either case, one has cash equivalents that could be withdrawn. If you take the dividends in cash or sell a security to raise cash, you have cash. Thus, it doesn't matter what origin it has. If I sell a financial instrument that later   appreciates in value, then this profit opportunity is lost. In the   case of a dividend, I'd still possess the financial security and   benefit from the stock's appreciation? One could argue that the in the case of a dividend, by not buying more of the instrument you are missing out on a profit opportunity as well. Thus, are you out to make the maximum profit overall or do you have reason for taking the cash instead of increasing your holding?" All that it is saying is that if you withdraw money from your account it doesn't matter whether it has come from dividends or capital gains, it is still a withdrawal. Of course you can only withdraw a capital gain if you sell part of the assets. You would only do this if it was the right time for you to sell the asset.
"Its not for US citizens - its for US residents. If the US considers you as a tax resident - you'll be treated the same as a US citizen, regardless of your immigration status. The question is very unclear, since it is not mentioned whether your US sourced income ""from the Internet"" is sales in the US, sales on-line, services you provide, investments, or what else. All these are treated differently. For some kinds of US-sourced income you should have paid taxes in the US already, regardless of where you physically reside. For others - not. In any case, if you become US tax resident, you'll be taxed on your worldwide income, not only the $10K deposited in the US bank account. ALL of your income, everywhere in the world, must be declared to the US government and will be taxed. You should seek professional advice, before you move to the US, in order to understand your responsibilities, liabilities and rights. I suggest looking for a EA/CPA licensed in California and experienced with taxation of foreigners (look for someone in the SF or LA metropolitan areas). Keep in mind that there may be a tax treaty between the US and your home country that may affect your Federal (but not California) taxes." "In a Traditional IRA contributions are often tax-deductible. For instance, if a taxpayer contributes $4,000 to a traditional IRA and is in the twenty-five percent marginal tax bracket, then a $1,000 benefit ($1,000 reduced tax liability) will be realized for the year. So that's why they tax you as income, because they didn't tax that income before. If a taxpayer expects to be in a lower tax bracket in retirement than during the working years, then this is one advantage for using a Traditional IRA vs a Roth. Distributions are taxed as ordinary income. So it depends on your tax bracket  UPDATE FOR COMMENT: Currently you may have heard on the news about ""the fiscal cliff"" - CNBC at the end of the year. This is due to the fact that the Bush tax-cuts are set to expire and if they expire. Many tax rates will change. But here is the info as of right now: Dividends: From 2003 to 2007, qualified dividends were taxed at 15% or 5% depending on the individual's ordinary income tax bracket, and from 2008 to 2012, the tax rate on qualified dividends was reduced to 0% for taxpayers in the 10% and 15% ordinary income tax brackets. After 2012, dividends will be taxed at the taxpayer's ordinary income tax rate, regardless of his or her tax bracket. - If the Bush tax cuts are allowed to expire. - Reference - Wikipedia Capital Gains tax rates can be seen here - the Capital Gains tax rate is relative to your Ordinary Income tax rate For Example: this year long term gains will be 0% if you fall in the 15% ordinary tax bracket. NOTE: These rates can change every year so any future rates might be different from the current year." This is subject to some amount of opinion, but I think that Treasury Inflation Protected Securities (TIPS) are closest to what you describe.  These are issued by the US Treasury like a treasury bond, but the rate is adjusted for inflation. https://www.treasurydirect.gov/indiv/products/prod_tips_glance.htm I see your comment about taxes.  TIPS are exempt from state and local taxes, but they are subject to federal tax on the income and on the growth of the principal. When you sell the stock your income is from the difference of prices between when you bought the stock and when you sold it. There's no interest there. The interest is in two places: the underlying company assets (which you own, whether you want it or not), and in the distribution of the income to the owners (the dividends). You can calculate which portion of the interest income constitutes your dividend by allocating the portions of your dividend in the proportions of the company income. That would (very roughly and unreliably, of course) give you an estimate what portion of your dividend income derives from the interest. Underlying assets include all the profits of the company that haven't been distributed through dividends, but rather reinvested back into the business. These may or may not be reflected in the market price of the company. Bottom line is that there's no direct correlation between the income from the sale of the stake of ownership and the company income from interest, if any correlation at all exists. Why would you care about interest income of Salesforce? Its not a bank or a lender, they may have some interest income, but that's definitely not the main income source of the company. If you want to know how much interest income exactly the company had, you'll have to dig deep inside the quarterly and annual reports, and even then I'm not sure if you'll find it as a separate item for a company that's not in the lending business. Where can publicly traded profits go but to shareholders via dividends? They can be retained by the company. "Some investment trusts have ""zero dividend preference shares"" which deliver all their gains as capital gains rather than income, even if the trust was investing in income yielding stocks. They've rather gone out of fashion after a scandal some years ago (~2000).  Good 2014 article on them here includes the quote  ""Because profits from zero dividend preference shares are taxed as   capital gains, they can be used tax efficiently if you are smart about   how you use your annual capital gains tax allowance.""" In a comment on this answer you asked  It's not clear to me why the ability to defer the gains would matter (since you never materially benefit until you actually sell) but the estate step up in basis is a great point! Could you describe a hypothetical exploitive scenario (utilizing a wash sale) in a little more detail?  This sounds like you still have the same question as originally, so I'll take a stab at answering with an example.   I sell some security for a $10,000 profit.  I then sell another security at a $10,000 loss and immediately rebuy.  So pay no taxes (without the rule).  Assuming a 15% rate, that's $1500 in savings which I realize immediately.  Next year, I sell that same security for a $20,000 profit over the $10,000 loss basis (so a $10,000 profit over my original purchase).  I sell and buy another security to pay no taxes.  In fact, I pay no taxes like this for fifty years as I live off my investments (and a pension or social security that uses up my tax deductions).  Then I die.  All my securities step up in basis to their current market value.  So I completely evade taxes on $500,000 in profits.  That's $75,000 in tax savings to make my heirs richer.  And they're already getting at least $500,000 worth of securities.   Especially consider the case where I sell a privately held security to a private buyer who then sells me back the same shares at the same price.   Don't think that $10,000 is enough?  Remember that you also get the original value.  But this also scales.  It could be $100,000 in gains as well, for $750,000 in tax savings over the fifty years.  That's at least $5 million of securities.   The effective result of this would be to make a 0% tax on capital gains for many rich people.   Worse, a poorer person can't do the same thing.  You need to have many investments to take advantage of this.  If a relatively poor person with two $500 investments tried this, that person would lose all the benefit in trading fees.  And of course such a person would run out of investments quickly.   Really poor people have $0 in investments, so this is totally impractical. "A dividend is one method of returning value to shareholders, some companies pay richer dividends than others; some companies don't typically pay a dividend.  Understand that shareholders are owners of a company.  When you buy a stock you now own a portion (albeit an extremely small portion) of that company. It is up to you to determine whether holding stock in a company is worth the risk inherent to equity investing over simply holding treasury notes or some other comparable no risk investment like bank savings or CDs.   Investing isn't really intended to change your current life.  A common phrase is ""investing in tomorrow.""  It's about holding on to money so you'll have it for tomorrow.  It's about putting your money to work for you today, so you'll have it tomorrow.  It's all about the future, not your current life."
