Evolutionary pressure in our society will tend toward women that have children, not women who don't have children.

If women all run business, go to wars, and the like. All of which implies that women won't have time to have children because it take 9 months to make a baby as well the maternity leave that come with it. It will be a population disaster if that were ever to happen. Pretty soon, you won't have a self-sustaining population.

In time, women like you will be the exception or already is an exception. Sad, but true.

Not necessarily. Birthrates in developed countries where resources are plentiful and infant mortality rates are low tend downward, not upward. Our species has adopted the strategy that it is better to put more resources into fewer offspring than the shot-gunning approach. We only need to maintain replacement levels or slightly above to be self-sustaining.

Apart from isolated examples in certain countries I don't think the world as a whole has much to worry about in maintaining replacement levels.
