Marx on materializim

The idea of the worker as a commodity has never crossed my mind before. Marx makes the argument that people work to produce goods in order to get money. In effect they are selling themselves as labor and thus turning them into commodities. I have never thought of it like this but it is absolutely true. In a country where most of our industry has turned to service related industries people do have to sell themselves. People do it every day. While Marx was thinking more along the lines of hard labor workers, today's society still does the same thing. Every day when a business man puts on his suit it is because he has to sell himself to his employer or client. Sales people have to gain personal trust by selling their image and experience. Even looking at resumes as an example, they are basically just menus for employers to pick the best entree. It is this ideology, that people need to sell themselves to make the most money, that is perpetuating the problem of alienation among society.
