to you too fam. It took me a while to get back to you on this, my bad.
The difference between the antebellum and today is that this mobility I speak of can be found in greater numbers nowadays. Not only because of democracy but also due to technology which makes entrepreneurialism more feasible to a much larger sect of the populace, what with the ease in communication and all that.
As for your point, I very much agree with it as my own point simply emphasized competition over cooperation. Both aren't mutually-exclusive as far as I know, and you obviously know it too.
Moreover my view isn't necessarily that people are naturally selfish/greedy. Instead I believe that given the limit of human's more valuable resource (time) + a willingness to make the most out of one's lot + human needs AND wants = competition becomes a very natural part of the human experience. And it can be found on any system really. Capitalism just places a very interesting emphasis on it, which appears to be very effective.
As for the dominant class conditioning behaviors and dispositions for its material interests, I believe that to be an unavoidable reality of the human experience. A reality that stops me from exalting democracy as the greatest human achievement, but yet does not stop me from accepting it's contribution to the aggregate of human growth in many frontiers.
I also believe that the non-dominant class also conditions some of the behaviors and dispositions for its material interest. Do you disagree?
