America's Class System

Marx’s “The German Ideology” gives deep detail about the division of labor; how it began and why is continues to function. He claims that there are only two class systems that exist in society: the bourgeoisies and the proletariats. He states that “the class which is the ruling material force of society is at the same time its ruling intellectual force.” He goes on to state “the ideas of those that lack the means of mental production are subject to them.” By this he is stating that the bourgeoisies are the ones with the capital therefore they are the ruling class and the rest simply obey.
I find this to be the exact case in today’s society. There are may be politicians that have come from poor backgrounds but they are indeed not poor today. I also see that though we claim there are several classes (lower, working, middle, etc.) the reality is that these are all just different levels within the proletariat class and the so-called middle class has been diminishing for the past decade. Keeping this in mind, do you agree with Marx’s two class system or do you believe that there are other groups in between? How to you see the future of the class system here in America?
President Obama just issued a pay freeze on all Washington D.C. politicians who make more than $100,000 a year. This means that while the working class will get raises throughout the year, these politicians will not. His justification is that “the rest of America in tightening their belts, so can we.” He also plans on giving a tax cut to those within the working class while increasing taxes on those that earn more than $250,000 a year. (Remember that he too is part of that tax increase.) Do you think that this will bring back what has been lost in our middle class? Putting your political beliefs aside, do you think that he is trying to punish those that have been in charge while rising up those that have been exploited?
