1930 was the stock market, 2000 was the dot com, 2007 was real estate (there's a bunch of recessions in between I'm skipping because I'm less familiar w/ them).
This time around...there's actually NOT a lot of exuberance. People are still scared and not getting ahead. Unemployment is at record lows but wage growth is stagnant, meanwhile people's basic expenses have exploded through the roof. Who has money to spare on stupid fads & bets? People are just trying to afford housing, healthcare, and education.
I feel like a lot of the talk around recession is simply people EXPECTING a recession and reacting accordingly, which will cause some downturn but won't impact the fundamentals of people buying shit in the economy.
I'm not saying we won't ever have a huge recession again, of course we will, but I don't see a current real indicator of it.
