Everyone is aware of the problem. On the one hand, multinational companies tend to use heavily underpayed workers in poor countries to manufacture goods they can later sell for loads of money in the western world. On the other hand, had these companies not done so, these underpayed workers would have been even poorer and may even be starving. The question is what can be done. It is unlikely that a company would increase their wages on their own, as this would give them a competative disadvantage as compared to companies with low wages.
At the end of the day there is always going to be poor people and rich people within the world, with the rich exploiting the poor. It will never level out, thats just a fantasy some unrealistic people have. Its harsh but thats life.
It's just the capitalist market economy.
