No people like you are bad for these people. People take the best job they can get, because you know what -- it makes their life better. Yeah working hard sucks, but you know what being in poverty sucks more. China is poor, to reach the standard of living found in the west (generated over decades if not centuries) they have to make up a lot of that effort. Technology/Productivity improvements significantly reduce the level of effort required, but eventually work needs to be done.
They can build cities, cars, etc -- but they need natural resource imports, so they must trade with the rest of the world. For some things it makes sense to purchase from the outside market, cheaper to purchase than make themselves, so once again they need to make something that the outside values. It's the most efficient use of their time.
As for possible inhumane treatment in the form of employer abuse, etc that of course is wrong and a different matter than just working hard.
