Guys a superior to women. They are physically stronger, etc...

I think that the middle class is the most efficient class, because they help the distribution of wealth.

i agree with you 100%. Most of the time people are born into these "classes"

Yes, the U.S. does have a class system. All over the news you here upper, middle, and lower classes. Although most americans are in the middle class, we still have people in the upper and lower classes.

Women and men are somewhat equal. I think this because women and men's jobs are different. Like some people for certain jobs are require a certain sex. Women get paid less. My opinion is that women face a lot of difficulty throughout life.
