I think people who choose not to have kids( not because of health reason) shall say a BIG THANK YOU to people who have kids. As their pension and retirement life will be supported by other people's kids.
I know several people who decide not to have kids, their logic is " Life is too short, it is better not to spending 20 years on the kids". Or "our current life quality is so good, I don't want any change". And they spend tons of money on themselves, e.g., 4 big vacations a year, golf every week, go to the Lady Gaga performance and similar things even they are in late 40 or 50s, and etc..
In Canada, the birth rate is under 2, that is because so many people(espically non-immigrates) chose to have none or 1 children.
If you have more than one kids, calculate how much money you spend on yourself and the spouse even if both of you work.
I read one article: DINK family would find they need more money to retire as they have used to spend much more money on themselves than people who have kids.
So I think people who have no kids need to thank people who have kids, at least in Canada. NOT the opposite.
The society always recognize the sacrifice parents do for the next generation. Sacrifice in finance, career, life quality. That is the fact, we could not ignore it.
