It's not just China
Unfortunately, abusive employment practices are rampant in many so-called civilized countries too. When I worked retail, 100-hour weeks happened several times per year, with 60 being the norm. Now that I'm in IT, I know many working over 60/week, with occasional 80+ hour weeks, for no additional compensation (salary). While it may be shocking to our European cousins, the US has very little in the way of laws protecting workers from excessive overtime, no mandated vacation, weekends or holidays. More and more, it's becoming the norm for companies here to drive people until they absolutely burn out or, as was the case with one of my coworkers, die. But, the hourly jobs don't pay the bills, so we keep at it.
