Here's the start

Amazon aggressively gained market share in part by long avoiding, and then minimizing, the collection of sales taxes. As it became less and less able to avoid collecting sales taxes—because it couldn’t avoid locating warehouses in more states—it learned that it could sometimes extract lucrative taxpayer subsidies for them, and methodically started doing so in 2010–2011.



Another part from the opener:

Public officials must recognize their communities’ value. They need to recognize that the prize on the bargaining table isn’t an Amazon facility: it’s more access to the local market for another aggressive retailer growing at the expense of existing retailers. To their credit, some of the public offcials we interviewed have a good sense of their bargaining power, informed by business basics, not incentives.
