I ignore much of your post simply because they're
mostly slogans against capitalism. Oddly though,
as a fire breathing capitalist, I find Biden to be
better than Trump for market capitalism.
The people voting for Trump aren't doing it because they think he'll be better for capitalism. They're doing it because they have lost all faith in the current social, political and economic systems, and they can see that Trump is willing to burn it all down. They have become THAT angry and hopeless. They know something has to change, and they can see that the necessary changes are not going to come from with the current systems of control.
Had you watched the video, Mr. Reich noted that when Trump first ran for president, the people that supported him also supported Bernie Sanders. Because they saw both of them as 'outsiders'; speaking out against the status quo. But the democrats wanted Hillary, making Trump the only option for them.
You claim you can't understand why so many people support such an obviously horrible choice as Donald Trump. The reason is that from their perspective, everyone else is even worse. Brcause everyone else, republican and democrat, will just mean more business as usual. And they will be driven even further into poverty and hopelessness. So will their children.
