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?
Citizens United and dark money PACs. As you can see from any given time Trump opens his mouth, people will belive any crazy lie so fast that an sincere politician without massive funding will be smeared with whatever the moneyed interests can dream up.

Texas just did that again a month or two ago.
