Biden's economy was an absolute disaster but the real problem started way back when America decided to print money out of thin air without anything tangible to back it up. So every President since the Nixon era has contributed, in part, to America's economic decline.
Want to know the value of the dollar? Look at the current prices of Gold and Silver. Look at America's national debt (nearing $40 Trillion).
Bidon was a complete economic wreck but Trump added $3 Trillion to the debt earlier this year. Nobody is innocent.
The bottom line is that our economy is in desperate trouble. No amount of political rhetoric or charts will convince American buyers that food, houses, or cars are more affordable today than they were 11 months ago or 5 years ago.
