I live in Bellevue so by supporting Amazon I'm supporting a local business. It's hard to imagine replacing most of the things I get from the site with someplace else. (Though it'd be nice to have a Micro Center.) I've even started getting more grocery products as Safeway/QFC/Fred Meyer up their prices, and the Redmond Fred Meyer closed which had the best produce. Etsy is mainly useful to me for the occasional copyright-infringing merch.
It's a local business to nearly everyone in the US. Anyways, it's not a local shop as the person you replied to called out.
Shopping at Amazon perpetuates the monopolization and consolidation of players in the economy. That means less competition. That means less incentive to improve the value they provide.
Seems pretty clear to me that shopping with Amazon makes things worse for everyone in the long run.
I wonder if people who live in DC think the same about their federal tax dollars, it’s roughly the same flavor of “local”
