How can I live outside of the rat race of American life with 300k?
An endowment is a large chunk of capital (i.e. money) held by  a university or other nonprofit.  It is meant to hold its value forever against inflation, and invested to generate income: from interest, dividends and appreciation.   They seem like a contradiction: closely scrutinized by Boards of Directors, managed to a high and accountable standard, closely regulated -- and yet, invested aggressively for growth: ignoring short-term volatility to get the highest growth long-term.  The law, UPMIFA (P for Prudent), requires growth investment, and says taking up to 7% of current value per year is prudent, even in down times when total value is shrinking.  On average, this lets the endowment grow with inflation.  7% is the high end of "prudent".  An endowment is watched, and the taken income is adjusted to keep the endowment healthy. 5% is very safe, assuming the endowment must pace inflation until the heat death of the universe. If you plan to die someday, drawing an extra 1-2% is appropriate.  There you go.  Invest like a university endowment, and count on up to 7% per year of income.  That's $21,000 a year. There'll be taxes, but the long-term capital gain rate at $21,000/year is pretty low.  That's pretty tight, but possible if your idea of entertaining is Netflix.  It would work very effectively for #VanLife, or the British version, living on a Narrowboat.
