I don’t think this something either party necessarily could solve. With the end of the Cold War and opening of China, the world had to absorb 500M+ new workers into the global system. That created a gap in the high-wage countries where middle tier and low tier skilled work shifted to those countries.
Now that workforce has more or less been absorbed and the workforce has aged considerably. For example production in China is almost as expensive as the US now, accounting for shipping, energy, insurance, etc. Now with new technology and shift in consumer demand to more immediate needs, I think we’ll see a shift in middle tier skilled labor back to developed economies.
