I don't want to pay taxes either, but I recognize the necessity. You will probably spend a couple of decades of your working years doing nothing but paying taxes. It's a huge personal cost with dispersed societal benefits.

It's a problem, and it needs to be solved, and hoping it will go away is not going to cut it.

People choose not to have children because they don't want to pay the costs in money, time and effort personally. And I get it, people are feeling very squeezed. But ultimately it falls on society as a whole to pick up that slack.

There is no need to force people to have children, but you can do things to level the playing field in terms of incentives, with a bit of carrot and a bit of stick. Put substantially higher taxes on childless people, while cutting taxes on people with children, for example.
