No they don't. Albany has repeatedly diverted tax revenues earmarked for the subways. This goes all the way back to Governor Pataki. State then forced them the agency to borrow and spend obscene sum on debt servicing. This is well-known and has been well-discussed.[1] The state currently contributes well over 500 million to the MTA.[2] So clearly money from the state does "see the coffers of the MTA."
For 2019 the MTA has deficits of just over 500 million dollars. This information is public and readily available.[3] It's worth noting this is the same amount the state was going to give to Amazon via a grant.
Despite whatever waste and inefficiencies at the MTA it most certainly does not have anywhere near the 19 billion dollars needed for Andy Byford's Fast Forward plan.[4]
>"Second, the $500MM was coming from the state. It would not, and will never, see the coffers of the MTA."
Wrong. The MTA already receives direct financial contributions from NY State via its' Metropolitan Mass Transportation Operating Assistance Fund.[5] This is not new either.
The actual facts refute your assertions.

Second, the $500MM was coming from the state. It would not, and will never, see the coffers of the MTA.
Third, if $500MM is such a big deal then the $2.5B in non-special incentives are a much bigger deal, and are getting completely lost in the misinformation that the entire $3B was a special deal for Amazon and that they would have got $0 without the dog-and-pony show.
