What is the main idea Marx is trying to get through ?

I think the idea of communism and individuality was to keep the rich 'Rich' and to keep the poor 'Poor'. Which in having this type of view only one type of people would always survive life and that would be the rich. A life lived like that is the most horrible to live because you wouldn't be able to better yourself or move into the upper class because you would be permently stagnated as a lower class citizen. Marx wanted the political and socialist to have complete rule over the people which causes the lower class to have no individual opinion on any matters that concern them but would be simply left in the hands of others whom knowingly have none of the poor folks concerns at hand.

When one thinks about it would you say we live in that type of world now? My answer would be yes we as a people are broken into social classes, upper class, middle class and lower class people. And in my opinion we are controlled by the upper class rich people . For example, Have you ever witness a poor man become president and be able to dictate what happens in America? NO you have not. Almost all if not all of our president came from an upper class family that was accepted enough socially that their peers ' other rich folk such as themselves gave that president a try. If they where not that socially inclined I don't think they would've stood the chance. Only because I believe the theory still stands of the "rich staying rich" and the "poor staying poor". Just like Marx the people that serve us believe in some of the same theories of life.
