Other reasons people don't have children:
- Socioeconomic disparities make it difficult to raise a family due to cost of living
- Uncertainty over the future with massive droughts (we have observed them), and ever increasing food scarcity imply that down the road, future generations will have a lot of issues to deal with, so why bring more people to needlessly suffer?
All in all, parent commenter assumes that young people are stupid, and fails to see that young people are generally concerned about their behaviour and the consequences. Commenter also fails to see that young people don't want to bring more humans to this planet because they don't want more people to suffer.
Bringing children to life is generally a very selfish act with dire consequences to anyone involved.
