Yes. That is what I said. I think it’s not a valid justification.
By way of analogy, let’s say we move to a point of tuition-free public college, which I also support. My taxes which go to support those colleges would be far higher than those of most people, but my kids, were I to have any, would receive the exact same benefit from a financial standpoint as people whose taxes contributed far less to none.
My property taxes are somewhere around $25k per year. They go largely to support a public school system which, as a person without children, I receive zero direct benefit from. Should I get a lower property tax because I am a person without kids despite having a higher income and higher valued property? Or should I be taxed relative to my ability to support the community? Should a family that makes a quarter of what I do but have four kids pay more than me?
