interesting
but lets be honest at the bolded; if theres another way of making state and local democrats lower taxes, im almost positive that no one on earth knows what it is

what are these other devices, and why are they not being used in NY/CA etc?
Well other ways to solve the market issues would be denser construction and zoning considerations geared towards housing, Treasury Department recently put tougher money laundering regs in place(good start), less tax incentives for ultra luxury developments, tax reform on condos and co-ops(their taxes are too low), increase the price and performance of EB5 funding, and there's probably some other things I'm not thinking of I haven't had my coffee yet.
Edit: They also been combing municipalities and services the last few years where a lot of savings can be found. I'm not sure how it is in other states but we have a lot of historical overlapping entities ie villages, towns, hamlets etc..
Well at the state and local level there are responsibilities that have to be funded it's fairly complicated but the property taxes have been capped for years at 1.5% or something similar. School taxes aren't capped but are voted on. I think Medicaid is put on individual counties depending on the number of recipients. At the end of the day low taxes are great but I'd rather have a greater standard of living and services than low taxes and the problems often associated with it. I also have to point out taxes are higher in suburban NY than in NYC. For instance in NYC you could have 10k a year in property taxes on a 900k plus house where in Long Island, Westchester, Capital Region you could have a 600k house and 10k a year in property taxes.
At the end of the day the local taxes/debt isn't the really the problem, the problem is the elimination of SALT and states/taxpayers that have local taxes getting soaked by this tax bill.
Trump has called the deduction “unfair” because it means high-tax states shift some of their tax burden to states like Indiana and Iowa. An October report from Thomas DiNapoli, New York’s state comptroller, revealed the state pays on average 50 percent more in revenues to the federal government per capita than Indiana and Iowa. The same report showed that states benefiting most from SALT are more likely to be considered “new donors,” meaning the state pays more in federal taxes than it receives in a fiscal year. The letter also stated that New York would be hit hardest by this elimination, as 3.2 million residents, primarily lower- and middle-income homeowners, claim the deduction.
I'm not familiar enough with California but suburban sprawl comes to mind
