That is astoundingly ignorant. That is the epitome of ignorant. First of all, capitalism does not create a “ruling class”. Everybody is completely free to do whatever the **** they want - including starting their own business.
Secondly, socialism oppressed the people through an awful ruling class. It doesn’t seek to “eliminate” a ruling class. It seeks to control everything and everyone.
Capitalism destroys the ruling class. Free and unfettered markets are a ladder of success that any person with talent and ambition can climb. This threatens the position of the ruling elite, hence the fabrication of idiocy such as Marxism, which is just Monarchist rule repackaged to appeal to the stupid and lazy.
The point of Marxism is to destroy the bourgeoisie, the middle class of merchants and entrepreneurs, so as to destroy the path of economic freedom and put the yolk of serfdom back on the masses. The goal is to protect the wealth, power, and position of the ruling elite from the usurpers who climb above their station.
Marx was a student of Hegel, Hegelian thought revolves around, in fact is consumed with the desire to restore the Monarchy and roll back the enlightenment. Hegel termed absolute and unquestioning obedience to the crown, or state, to be an "ethical life." Liberty in any form, questioning of the absolute rule of the monarchy or state was therefor immoral and unethical.
