That's a lot of words to say that a lot of net worth is tied up in hilarious memecoins and crypto (literally all stocks right now) and when the correction comes/happens that they won't be feeling the long term damaging effects of losing that net worth.
I get that it's great that they invest more, but part of them investing more and having 401k's etc is that it's all a real ticking time bomb when stocks just stop continuing to "always go up". Stocks don't always go up, the S&P 500 has a long term rate of return yadda yadda, you know that buying the index isn't a real thing? if you bought shares in the S&P based on corporations inside of it that the game wouldn't look like that because the ones that fall out have lost substantial value. The cheat code for the index is that they remove things that make the index do things they don't like over the long term.
Stocks in fact do not always go up and a lot of stocks are actually terrible speculative investment vehicles that a lot of people collectively depend on to get lucky so they can support their net worth. There are a few stocks that have survived the test of time and have survived through cycles, but there's mostly a bunch of companies that haven't done jack shit or outright died in the GFC. Those stocks are eventually removed from the indexes or whatever people are doing, but they aren't removed from the real value lost in people's portfolios. It's why investing in the stock market isn't a guarantee for money and it's why Warren fucking Buffett is sitting on 300B+ in cash right now.
