There's only one thing that is worse for people than international capitalism exploiting the workers of a poor country. It's that international capitalism does not exploit the workers of a poor country.
Poor countries can be roughly divided to two classes. One is "developing country", and its main characteristic is that it doesn't develop. The other is "emerging market", and it's the one that develops.
Eventually, that may of course be something that we later start to dislike. At one time, it was every third-world-activist's dream that China, a country with socialist government and hundreds of millions of extremely poor people, would become richer, that people would not be starving any more. That was to be achieved through socialist market economy.
Now that the dream has come true after China adopted capitalistic communism, many of these activists are uncomfortable: they are taking our markets, they are making the workers in formerly rich countries unemployed - because they work harder.
