20th Century Austrian-American economist and devout anti-communist Ludwig von Mises clearly believed what he said at left, and there were plenty of examples in the 1900s to support his concept.

Now, 50 years after his death, we wonder what he would think about today’s United States.

The U.S. has an economy that’s as close to unadulterated capitalism as anyone could imagine, but we have a president who is most definitely an authoritarian, a would-be dictator.
