The problem with Capitalism....real Capitalism....is that it is resented by people in power who personally gain from having the government "interfere with" (manage?) various free markets. Government is always years or decades behind the trends, since it it based on past experiences and results. Free markets tend to change very quickly.
Our president, as well as a major part of our society doesn't really believe in Capitalism or perhaps more accurately, believe that all Capitalism is Crony Capitalism.
Ardent Socialists/Communists would often claim that the USSR or China were not "good examples" of their preferred political organizations. In the same way, I might claim that the US is not a very good example of how Capitalism works, because it is constantly being thwarted by Socialists/Communists.
