"Since COVID" is a bad baseline, I would draw a parallel with someone who's condition "stayed stable since they entered the hospital a few days ago". It is too recent and the situation pre-COVID was quite bad. The US is the most indebted entity [0] in history. But it is not obviously the most productive; since that title may sit with China now. It is a precarious position.
