No it won't. "Sears" used to sell high-quality own-brand products, then eventually outsourced to China, now it's gone.

Amazon is the next Sears. Eventually something will come along with a selection of curated high-quality products, everyone will celebrate how amazing it is, and it will replace Amazon. Then that too will eventually need to pay back investors and shareholders, exploit its dominant position in the marketplace, and race to the bottom, again.

This is the natural cycle of commerce in capitalism.
