Even before the virus, Trump kept touting ho great the economy was, but the reality is only the stock market was doing well. This was due to the huge corporate tax cuts that were supposed to trickle down to the average American, but never did. The corps just bought back shares of stock and gave themselves bonuses. This is what kept the stock market going.
The unemployment numbers were deceptive as well, because stagnant wages could not keep up with cost of living increases/ child care, more people were taking multiple jobs.
By giving the big tax cuts to corps, it means the USA no longer gets all that money, so we either have to cut spending or go deeper in debt. Spending increased substantially under Trump, so we were in deep to the mob.
If you're wondering why Trump has been criticizing China so much lately, it's because he's considering defaulting on their loan. This is what Trump does, he borrows money and never pays it back. He took huge personal loans from Russia and could not pay them back, which is why so many people think he struck a deal with Putin. Now we're hearing he may have personal loans with China as well.
So the virus definitely hurt the economy, but it was bad and getting worse on its own before all this.
