You need to be explained why $1.5B in public assistance to a trillion dollar ($700B+ today it seems) company is bad?

I'll try.

It distorts the competition, ESPECIALLY in the case of Amazon which more or less competes with every retailer everywhere.

It sets a bad precedent (yes, yes, water under the bridge) of big corporations expecting these benefits any time they feel like moving around.

NYC has better uses for the money.

It doesn't need the goddamn money, because it's one of the most successful companies in the entire world, ever. It can finance its operations by itself with absolutely no problem whatsoever. It's ridiculous they're even asking for public assistance.

This is a race to the bottom. Sports stadium construction incentives are good examples of this.

You know, I was going to respond to you by saying that there will always be Amazon business without a new HQ in a place. However, I thought about it and it is certainly possible that they would test new and interesting things in markets around their HQs, potentially providing unforeseen benefits for the residents around them and markets around them. While the whole package deal still seems like a net negative and shady to me, that certainly does fall into a potential (though very not proven) positive category.
