You're comparing a country with a little more than 5 million people to a country with ~328 million.Bruh.
If you haven't realized, this type of progressive taxation system exists around the world and works. In Finland for example, there is a system which taxes the rich much more than the less rich, and as a result healthcare, university, school are all free. Not saying this is the way that American could go, but rich people stay in these countries because although they pay more tax, they still get benefits.
Right now, economic inequality is so bad in the US that the top 1% make more than 39 times that of the bottom 90%, which is insane to say the very least. What is being done as of now to reduce this inequality? Very little. If you wanna talk about it being bad for the economy then consider the fact that over 61% of americans say that there's too much inequality, which leads to unstable markets potentially.
The reason those people are in the 1% is that either they made something people like or someone in their family did. The fact is if you don't like people having that much money stop supporting them. Purchasing things on amazon supports them, using your iPhone or MacBook supports them. You aren't gonna make them not in the 1% by taxing them a large amount instead they will either keep using the loopholes or move out of the country. They have the money to move anywhere and there are many countries around the world that would take them not including they could just buy a whole island and say screw it I own an island.
