The vast majority of the so-called subsidy is welfare, which has been pushed by urban politicians.
If you don't like the costs of the programs that you push, look in the mirror.
I've no objection to making welfare a county-level thing, so cities can pay what they want (and are willing to fund) and suburbs can pay what they want (and are willing to fund).
Yup. Making a generalized statement about a widespread, general phenomenon:
Urban centers subsidize everyone else, suburbs are freeloaders.
This is really basic, uncontroversial information.

Same thing happens at the local level.
