FWIW, I think it’s more about a certain $2.3 billion shortfall...
There may have been $2.3 billion in tax breaks extended to Amazon, but I don't know that this would be considered a "shortfall" when all the numbers are added up.
And I’ve wondered from the beginning whether the HQ2 thing wasn’t really a ruse to try to screw more tax money out of Seattle and/or Washington state. If, in the next few weeks, months we hear that Amazon is getting some additional tax relief from either, both, guess we’ll know.
Wrong.
The shortfall will occur now that Amazon won't be paying anything in taxes, because they aren't moving there.
