Is the benchmark for wealth and a prosperous life not having children? If this paradigm is true, then humans would have become extinct long ago. The choice is yours do you want to die leaving behind a lot of wealth that will be taken by others, confiscated by the government, given to institutions, or to your descendants?

Economic perspectives do not always align with basic physics and mathematics. If the current mindset is that “those who are established should not have kids” then be grateful to your parents for not believing in that principle, because if they had, you wouldn't have been born, right?
