I’m not sure if it was a typo on your part, or you might be misinformed of what the actual deal was that was struck. From TFA;
“Amazon was to build their headquarters with union jobs and pay the city and state $27 billion in revenues. The city, through existing as-of-right tax credits, and the state through Excelsior Tax credits - a program approved by the same legislators railing against it - would provide up to $3 billion in tax relief, IF Amazon created the 25,000-40,000 jobs and thus generated $27 billion in revenue. You don't need to be the State's Budget Director to know that a nine to one return on your investment is a winner.“
The crucial point is that there is no cash to bank! The politicians statements that the “money could have been better spent on xyz” was a lie.
The deal was to reduce taxes on future revenue if and only if Amazon met specific (lofty) investment and job creation requirements.
”Make no mistake, at the end of the day we lost $27 billion, 25,000-40,000 jobs and a blow to our reputation of being 'open for business.'”
