Modern China is a vastly better place to live than China of 60+ years ago. Many countries are nicer places to live, but 1+ Billion people are simply better off making the “exploitation” narrative ridiculous.
Porque no los dos? Given the number of billionaires in China, it can both be true that workers are exploited, meaning they could earning more for less hours, and that the living conditions are better on average and possibly medianely than the local minima of 1966.
