Well the Chinese knock offs usually appear way before the Amazon basics one (I agree the gap here is shrinking).
So assume Amazon gets ‘taken care’ of magically - what’s the solution for the bigger problem here?
Unless we go back to a world of strong nationalistic sentiment where customers are willing to put their money towards’Made in USA’ - I don’t know how this gets solved. Bezos famously said ‘nobody wants to pay more for a thing’ (paraphrase).
