It's not really a story is it? Output is a function of capital, labour and productivity. Double cost of labour and those that get the most productivity out of capital gain competitiveness. Who is relatively capital intensive? Amazon. So it's a pretty factual story economics-wize. There's no doubt labour is better of in the short run with double wages. I would not doubt the effects in the long-run but that's part belief. The market structure will change, less capital intensive firms will drop out. That might be brick and mortar stores (note: bricks are capital but bricks are not really productive in the sense meant above).
