I just read that the economic inequality gap in the USA is now worse than China and ninety-one other countries. I don't doubt it.
I think The Wobblies (Industrial Workers of the World) had the right idea of one big worldwide union. A fantasy perhaps, but if we could organize all the workers in the world into one big union and then demand one worldwide minimum living wage and if any corporation doing business in any part of the world didn't pay that wage the whole worldwide union goes out on strike until they do.
Now that would certainly lift everyone's boat, eradicate almost all poverty and eliminate moving businesses around the globe looking for the lowest paid most exploited workers, etc.
