Sure, but my contention is that even the small things are of worse quality in the so-called "high purchasing power" countries, which is the main reason why they are cheaper. There is no actual arbitrage or difference in "purchasing power", just that the market is optimized to serve a different price-quality point.
The main reason they are cheaper is that labor costs are lower. The barista at your local cafe is making 50x what a barista who does the exact same thing would make in Nairobi. That doesn't mean your coffee tastes better.
