No, but you can't simply extrapolate bad news ad infinitum.
But we DON'T have a stock mania or even a real estate bubble. The stock market may be overvalued but it's not set to collapse. Valuations are NOWHERE near 2000 or 2007 levels in terms of P/E or leverage. Not even close.
As for real estate, it's pricey and certain areas are overvalued, but it's not a bubble. A bubble was 1990 or 2007. Check out the supply of new homes relative to the population: it's DOWN by 30-40% while our population is UP by 30%.
The extent, no....but the direction, yes.
Unless you can tell us WHEN this collapse is coming, it's useless, WC. If it happens in 75 years, anybody waiting for Armageddon is a fool.
The U.S. has favorable demographics, private property rights, the rule of law, mobility of capital and labor, etc. We have dozens of world-class tech, medical, and other companies -- we lead the entire world. Europe has many continental problems, China is run by a 1-party authoratarian monopoly. Economies and financial markets just don't collapse, they collapse relative to internal valuations or compared to other countries metrics. The U.S. is by far the best house in a lousy neighborhood.
FRED data is interesting but doesn't tell the whole picture. Median figures are just that and don't show the upward mobility of Americans over time. You are assuming income, net worth, and mobility are all static.
