If the majority of voting Americans' lives got better in Trump's first term, then Trump would have won in 2020, but he got blown out losing by 7 million votes.

Cleaning up the mess Trump left was painful. The unavoidable consequences of global disruption of the economy (ie reduced supplies of goods) was a bit of inflation, and while Biden achieved the best recovery of any developed nation with the lowest inflation and very high wage growth among the bottom 40% of income earners, enough voters were turned off by inflation and by rightwing efforts to make voting harder that Donald Trump was able to just barely pull out a victory.

Trump is eliminating guardrails left and right and unsurprisingly is crashing things much faster this time around.
