Are all the products I purchase produced within the high-wage country, or are many of them produced in the low-wage country? If so then I'm shielded from paying high-wages to a great degree and so get the best of both worlds.

Lots of people retire to (or work remotely from) low-wage countries (or regions) because their money will go further there.

Manufacturing keeps moving to the next poorer country as wages rise because people don't want to pay more for their t-shirts or other manufactured goods as countries industrialize.

That only goes so far. You can't offshore building your home, for instance.
