He literally proposed a wealth cap for which a single person can hold, minimum wage before it was a thing (the minimum wage was first introduced in 1938 for those who did not know). So, he went against capitalism in a way which doesn’t even exist in China today. Even in China, there is no wealth cap or something close to it. For example, Bernie Sanders wants to increase taxes in order to provide more public services which means he is not going against capitalism but only increasing taxes. Why isn’t anyone doing this now and go against the establishment? Why doesn’t anyone try going out of the boundries of capitalism?
I think Elon Musk’s purchase and weaponization of Twitter, as well as how the CCP have been operating TikTok, are great examples of the impact wealth has on the USA’s politics, but I don’t believe it’s the end all factor in deciding outcomes. Otherwise, there wouldn’t be such a close and even split between the GOP and DNC, it would just all be GOP.
