That's at least in part the purpose of the tariffs: it helps to equalize the wage gap. I don't see it such a morally bad thing either: China is a communist country, the labor force is essentially slave labor to them. Wages are artificially held down in order to keep companies coming there, destabilizing manufacturing in the rest of the world in the process.
The article uses horribly flawed logic when it says bringing some of the production onshore isn't a 'panacea'. It quite clearly IS a panacea if it helps control costs by off-setting the impact of the tariffs. And it's a win-win because it brings jobs back; a couple bucks more for a GPU is a fair price to pay if you're the one looking for work. What quite obviously is NOT a panacea is foolishly depending on the largesse of government exemptions.
I also like the idea of re-sourcing to less hostile countries than China: Singapore, Malaysia, even Vietnam. And why not Australia? UK? EU?
