If you’re making median income outside places like LA/NYC/SF and don’t have children, it should be pretty affordable.
Did you ignore the fact that a large majority of Americans don’t have any money to invest because they’re living paycheck-to-paycheck? Do you think they all live in those sorts of cities? Wages have been stagnant for decades now. Housing prices, rent and food prices are through the roof everywhere in the country, as is the (always) variable-rate APR on things like car loans. American household debt is $16.9 trillion.
Most people simply do not have money to save or invest. They’re not getting paid enough, essentials are too expensive, and they’re drowning in debt.
