That will never happen, because everybody in the West wants to get UK
plumber salary and work no more than 30 hours a week, yet purchase
everything at Aliexpress prices. So if everybody's work is expensive
who's going to produce anything at low prices?
It's financial pyramid, when China workers will raise their demands, the
pyramid will colapse.
