Imagine you make 2.5 million/year. Why should you pay 1.25 million as taxes? Are you being taxed for being wealthy? Isn’t it punitive? What services do you receive that is worth 1.25 million?
But imagine you make 60k/year. Roads, infrastructure, essential services, public schools for a family of 4 with 2 kids does make sense. A larger family benefits more as they get more than they contribute.
Our tax system incentivizes larger families and redistributes wealth. It works if there is a healthy middle class. In CA the very rich is thin but they also support a larger proportion than other states.
When we are looking to hit 9 billion soon, it’s probably not best to incentivize rampant population growth and large families.
