The word "capitalism" has become rather useless, unfortunately. Those who are enemies of it, have a version in their heads that is worth fighting against. Those who are supporters of it, recognize how it has improved human wellbeing more than almost anything else in modern history (and yes, they have a different version of the word in their minds as well).
Comparing masked violent authoritarianism with "an economic and political system in which a country's trade and industry are controlled by private owners for profit, rather than by the state" is beyond me to understand.
I subscribe to every word.
