It means that when you look at government revenue vs expenditure per square mile, urban dwellers are massively subsidizing surburbanites. It's mainly because maintainence of roads, parking, and utilities for a spread-out surburbia is vastly less efficient than it is for a tightly packed city.
We all pay taxes, I don't see an issue. I pay significantly more taxes than people who are living in more affordable/dense housing in the city - both in property taxes as well as the fact that I earn a higher income. I am subsidizing lots of other people in my community.
There are loads of people who believe this but who are mistaken. Typically they are underestimating the value of services delivered to them for free at the point of use. We don't know your individual situation of course, but it's true in the aggregate.
Sounds like a problem with the system, and not a problem that should be projected/blamed on individuals. No one likes paying taxes, but I believe most people are willing to contribute to the common good when they know that it is actually going towards the common good. I feel this way at least and have a decent sense based on anecdotal conversations that a lot of others do too. I am willing to pay more taxes if I know that it is going to directly help people around me, and raise the quality of my entire community. Unfortunately that is often not the case.
It is indeed the system, and you (to no fault of your own, probably) are part of that system. NotJustBikes, while a little anti-car-propogandaey for my tast, does a good just explaining why it'd be basically impossible for suburbia to ever pay for itself: https://youtu.be/7IsMeKl-Sv0?si=F-ePxGzjUjHrSJCR
