There are checks and balances(elections) to deal with subsidies within a state. Child care, school, roads...etc..don't like them, vote for the other party.
There is no such mechanize for state to state other than stop deductions of the taxes paid at the fed. level.(Nevada can't force California to the negotiation table for stupid spending).
You are mixing them up.
