Markets encourage some behaviors and discourage others, which may be not always in the best interest for themselves and everybody else in the long-term, because individuals often think and act too short-sightedly. That's all I meant.
If you think this is a big problem for markets, where people decide how to allocate their own resources for their own benefit, you should see how big a problem it is when people get to decide how to allocate other people's resources for other people's benefit.
Maybe the root of our divergent assessments is that you believe it is a choice like many others. I rather feel that childbearing is a permanent and important aspect of a society. Statistically, every woman needs to give birth to slightly more than 2.0 children in order for a population to remain constant.
If you like childbearing, you are welcome to encourage it with any resources at your disposal. I just ask that you don't attempt to commandeer other people's resources to use in your social experiments. There is nothing inherently good about a constant population. Some may have good reasons to prefer an increasing population, others a decreasing one. You are welcome to use your resources to achieve your goals, just please extend to me the courtesy to use my resources to achieve my goals.
I have no objection to others incentivizing or dis-incentivizing childbearing as they please. So long as you get others to go along with you by the strength of your arguments rather than the size of your gang, you have my full support.
