in the real world domestic workers don't all go on to become farmers (oops that's dumped onto by subsidized western businesses too) or some other business... some degree of protectionism has consistently worked well to the extent it's arguably necessary*. And don't take this as me defending sweatshops either ;) but a moderate degree of protectionism and public investment has very consistently allowed countries to move beyond the absolute basic "we have sweatshots and scrap out old electronics and recycle garbage" stage of development. Neoliberalism and free trade will suck away any public investment you give it the opportunity to, and engineer around any comparative advantage you can find.

In no way is being poorer the solution to not being able to afford things.
