> it’d force Amazon to show the country of manufacture

I don't think many people would care.

I’m reminded of that company that added a Made in USA option of their product that you could select next to the normal price and nobody would buy it at any price premium.

Like, literally nobody.

I wish I could remember where that blog post was, I think it came up on HN.

That experiment had an 85% price premium said the item was identical and some people still added it to their cart.

Saying people wouldn’t pay any premium is very different than saying they won’t pay an 85% premium.
