I think you're just referring to California. If you follow the 4% rule, that 2 million works out to 80k a year. The 4% rule basically says that if you withdraw 4% a year and invest the rest of the money, it should last the rest of your life as investment returns have averaged 8-10% over the long term. Doesn't go far in CA, but there's a reason certain states are popular for retirees, much lower cost of living. Lots of retirees also become expats and live in other countries where cost of living is even lower. Of course with inflation, that might not hold for long.
Seniors cannot play the long game. Heck, most of the BITOG prognostigators have a huge equity market crash comming, right?
But if you are 65, have housing under control, have $2M and play your cards right, you should be OK.
FYI we are talking about very few people. The median net worth of Americans over 65 is about $260K.
Another way to look at it is, around a third of the US wealth (31.4%) is owned by the top 1%, which is almost 16 times more than the bottom 50% who own 2% of it.
Please don't wait until you are older to start saving! Get scared people! Invest in yourself!
In theory, we all want to have just enough money so we are done spending our last penny when we die. In practice this means half the people will likely die on the street homeless and the other half with left over money in the bank.
I'd err on the side of being safe and make sure the return on investment of my asset is increasing above inflation + living expense, rather than withdrawing 4% a year. All it take is one wipe out event and retiree can be wipe out with nothing to fall back to, don't be that guy.
