Getting "Amazon to pay its fair share in taxes" is a pipe dream. The United States is, by design, a race-to-the-bottom internal free market. Any given county has to balance tax rates with attracting/keeping businesses in the county. So the tax money coming in is what it is. Especially if you're one of the 99.9% of counties outside the Silicon Valley halo. The policy question is how to spend that tax money, and what modes of analysis you use to justify your spending. Romantic notions are not a valid mode of analysis justifying expenditures of tax money.

Amazon operated under a loss for so long they have a ton of carryover tax credits

The fact they are not paying taxes right now is not a bad thing. We've benefited from them pushing commerce for the last decade
