Claptrap. The middle class was eroding long before the current run of inflation. The inflation is making things worse to be sure, but it is not a major cause.
The deficit didn;t just start with Covid, nor has the printing of money. Between 1970 and 1982, inflation caused the dollar to drop in value by 60%. So if you have $100,000 in cash in 1970, it would have had purchasing power of $40,000 by 1982. Between 1982 and 2021, the value of the dollar has dropped another 65% so that original $100,000 would only be worth $14,000.

Money printing raises the cost of assets like the stock market, real estate, commodities, artwork, pictures printed by Ansel Adams, etc. The rich hold those assets so money printing helps them the most. The rest of us have to rely on our salaries which get reduced in value due to inflation. Since the government reduced interest rates to practically 0%, you can't even make a few bucks from that anymore. In the old days, banks would give you 3% plus a free toaster if you opened an account. Today, you can't even get a toaster.
Regular people have to work harder, make our wives work to make ends meet, and hope our daughters marry rich guys. The middle class is being decimated by inflation and government deficit spending. It turns out all that free stuff isn't so free after all.
