Thus, the only reason it is "in your best interest" is a prisoner's dilemma. https://en.wikipedia.org/wiki/Prisoner's_dilemma
Any city has two options: A) hurt yourself by making big concessions, B) don't do that. (Obviously also various degrees of A, but that does not matter in the following).
Ideally for your city and all cities, every city goes with B) and you get the deal by virtue of what should matter (existing infrastructure, location,...). However, if another city "caves" and offers A) they improve their chances, so what happens is that all cities offer A). That decision is "in your own best interest", but everybody is worse off than if nobody did that (same for bribery and paying "protection money" to the mafia).
Thus, yes I am opposed to Amazon receiving the benefits of these programs. However, instead of repealing them outright, they should include a ceiling.
If that sounds absurd, I certainly think it is. Local governments shouldn't be trying to "profit" by taxing its residents and companies. The whole purpose of local taxes is to best serve local residents and companies. If a city/state can better serve its people by lowering its taxes or by offering tax credits for specific programs, it should certainly do so, even if there's no competition involved. There is no prisoner's dilemma here.
I wouldn't have thought that I need to pay companies to exploit my local labor pool. I'm not buying something from them. They're buying something (work) from me.
Since you seem so opposed to tax breaks for big corporations, have you also lobbied for repealing the Excelsior and REAP programs? Or do you get upset only when these programs are applied to Amazon?
