Women may earn less in the workplace if they have a child. In regards to altruism and the recent readings about women being care-givers, I know a woman back at home who works on Wall Street and is definitely in the upper, upper middle class. Her husband is the housewife and their kid is a junkie with no morals or vision of the future, a future convict. I wonder if he would be this way if his mother stayed home all the time. Whether it's equal or unequal is irrelevant.
Nothing frightens people more than the prospect of losing their jobs and their income.
This fright shall increase work productivity. In an ideal society there should be an equal balance of efficiency and equality. However, human nature will always stop us from attaining this goal. In the 90s, money is what everybody wants in the ghettos, the middle class, and the upper class. It is a very competitive world.
