"Roughly 58% of American adults own stock"
This includes my teenager, who socks away $30/week in a VOO fund account. But yeah, no one can afford to "own (shares in?) the robot factories."
The median American has a 401k, yes. The median amount of stock owned is, I believe, $40,000 -- so, at the recommended annual withdrawal rate, that puts you at $1,600/year of spending money.
Let's assume that the stock market 10xes in the next decade, then the median American stock owner can get out $16,000/year.
Some other interesting stats for context:
* About 87% of adults with a household income of $100,000 or more own stock; compared to just 28% of those earning under $50,000.
* Only about 37% of adults hold stocks, bonds, or funds outside of a retirement account.
* Between 55% and 60% of Americans live paycheck to paycheck and are one large expense or missed paycheck away from homelessness.
* While some paycheck-to-paycheck workers technically own small amounts of stock, the actual value they hold is minimal.
* The wealthiest 10% of Americans own roughly 90% to 95% of all U.S. stock value.
