Amazon deciding how it will best benefit society is exactly like a billionaire arguing that only she should say where her tax goes. Ah, but that's not how it works. It's not a $1 for $1 tradeoff -- you can avoid paying 35 cents of tax by contributing $1 to a charity (or, in the case of Amazon, subsidizing consumers by $1).
