Why is there such disparity of max contribution limits between 401K accounts and regular IRA accounts?
The investments offered in 401K are usually limited to a selection of mutual funds offered by a 401K provider.  The 401K providers and the mutual funds charge fees.  The mutual fund industry has a lobbying group that will push for increased 401K contributions to direct money into their mutual funds to collect fees.  The top 401 K provider in 2005 was fidelity.  It managed $337 billion in 401Ks of which $334 billion was directed into mutual funds. Although I would have to use some of the same providers to open an IRA, I would not have to invest in the providers' mutual funds when I open an IRA.  I can buy a stock and hold onto it for 10, 20, 50 years inside of my IRA.  Thus, the only fee the investment company would collect from me would be from when I purchased the stock and when I sold the stock.  Not nearly as profitable as mutual fund fees.
