Germans and Japanese don’t make socks for $10,000/year. Our former au pair lives in a small town in Germany. She was tracked into an apprenticeship program at 16 (off the college track), but now in her early 30s has a solid white collar job doing logistics for a baby formula manufacturer. Her boyfriend works in logistics as well—a big industry in a country that makes things.
By contrast, GDP is higher in the U.S., but is that real? As a corporate attorney, I make probably double what I would in Germany. Pay differentials seem to be similar for other knowledge-economy jobs like software development, marketing, etc. Our laptop class makes tons of money compared to their counterparts in Germany or Japan. But is that a good thing?
