Maybe because the EU doesn't have Trump?
Joking aside, but I remember well when Trump claimed that COVID-19 was something like the common flu that would disappear with the arrival of spring. At that time, there were less than 20 confirmed infected people in the USA, but the fact is that no mass tests were conducted. Ignoring the problem and the stubborn policy of "No one can do anything to us" with the mass protests that took place due to the pandemic led to the virus spreading to the point where it can no longer be controlled.
The economic side of the story is quite clear, everyone, including the USA, pays the lockdown tax, and it should be added that the USA is in a trade war with China and that things are not going well when it comes to Russia. Taking into account all the other countries on their blacklist, it turns out that they have bad relations with half the world - while the other half cooperates with them out of fear.
But as someone has said before, there is no need to worry about the USA, they will get out of the crisis one way or another.
