That is the redefinition trick of Liberalism: the Liberals often redefine Capitalism so Capitalism can take the credit for productivity from people that work against the Capitalism system or shift the blame of Capitalist problems to an individual or group. The quoted argument in opening post assumes that Capitalism is a market economic system that produce all the innovations in the modern period which contradict the Liberal practice to use Capitalism as reference to plutocratic command economy. The Capitalists spread the redefinition of Capitalism in schools to convince the workers to support Capitalism from the ignorance that their current free riding plutocratic system in the leading Capitalist country is actually Capitalist.
