Agreed completely... However, some do fall through the cracks. I know a 31 year old yoga instructor, living in idaho, who's and staunch critic of capitalism. In my experience, the only people to remain critical are those who fail to succeed within the framework of the market economy. I believe that my prof is the same.
Personaly I think that as some people are leaders and some are followers, most are followers, I think that this is a direct result of marketing by corporate types and upbringing.
What I mean to say is that even tho the corporate world is obviously capitalistic, their marketing plans for the most part tend to lend themselves to the pack mentality, "keeping up with the Jone's" ( again a big stretch) What the group has i want, what the group wants I must have. The very same idea can be used in support of, or as a weapon aganst "Individualism" depending on your goal at the time. Basically our society reveres the individual but markets to the group. Independent thinking by consumers is bad for corporate statagy.
Upbringing, I always tried to impress apon my daughter the need to ask questions and like myself she has no need to follow the pack.
I guess after all this rambling my point is both marxist and capitalist philosphy have their own brand of dogma, however all of it is based apon the individual and or group mentality. It is far simpler to say everyone gets a fair share, however impractical that may be in reality. At the same time that the marxist makes promises that are not possible to obtain, capitalism does the exact same thing as it requires "Haves" and "Havenots", no problem if you fall into the "Have" catagory, just a matter of perspective.
The irony is tho both these systems depend on the same thing, group exceptence, it comes down to individualism, which if taken to the extreme is also doomed to failure.
