Earlier quoted context omitted.
There are other, safer, kinds of funds beside stock funds. It sounds like what you want is a fund holding government bonds. Those are pretty safe, and will probably give you better return than the bank.
US government bonds (ten year, so plenty of short term price risk) pay 2.16%. If you are in Europe, German government bonds pay around 0.8%.
If you have 1M$ and want to live on that, and you're good enough to live with 25k$/yr, you need to consistently "extract" 2.5% on that capital, that means you need to consistently get 4.2% every year. And this exposes another issue: even if you have a safe investment that can give you 4.2%/yr on average, that's not steady, so if some years are bad (or really bad) you need to eat into the capital. If these happens for too many years in a row, the capital could be reduced enough that you need to get higher earnings to counterbalance that.
I'm not a finance expert so feel free to show me the fallacies of my reasoning!
