US is so poor that president trump constantly attack China. Because China is so rich that they can buy the entire Africa, they can buy the entire existing technology, they can invest into best new talents, they can invest into 5G, 6G, 7G, they can build the best spaceship with all the income they received from tax money.
I'm being honest here, I don't have the attention span (or even the necessary interest) to read a long rant like the OP here. But Trump attacking China doesn't really have much to do with how each country's economy is performing relative to each other--nor is the United States "poor".
I don't know what the real truth is behind how this strain of coronavirus got released into the world, but if it originated in China then that's what happened. Trump is being unreasonably antagonistic every time he refers to COVID-19 as "the Chinese virus" even if it's true. If we eventually find out that the virus was released maliciously or there was some sort of coverup, then that's another discussion but as of now not all the facts are known.
I'm not a big fan of China, believe me, but I'm not going to pretend that I'm outraged that the outbreak started there.
