As a Norwegian I find this quote from him the most descriptive:  
"Donald Trump says that this is a socialist or Marxist government, Kamala Harris is actually doing just the opposite of that, creating a free economy that works and people can grow into the middle class,"

Without government intervention you wouldn't get free market/economy. You'll just get another boss controlling the market. It will be competition until oligarchies form. After that they control the market, and they don't have to worry about getting voted out. And unlike government they have a vetted interest in squeezing as much money out of the market as they can,
