What incentives does free-market Capitalism offer when laissez-faire CEOs constantly ship the jobs overseas?

[Le Socialiste]

Very few people actually move up in the economic/social ladder under free-market Capitalism. In fact, most statistics show that people born into their respective classes are more likely than not to either remain in said class or move down a class. Couple that with the fact that industries and corporations are able to legally move jobs overseas for less pay and less cost, and you have a disaster waiting to happen. I'll ask the question again: what incentives does free-market Capitalism offer to the lower working classes?
