(I just deleted my comment, let me try again).
I find it frustrating that you associate that with capitalism and presumably "not that" with socialism. These terms are so broad you can't possibly say that outcome will or won't ever happen with either system.
Blaming capitalism for all the world's woes is a major oversimplification.
If you look at the theory side of both... Capitalist would tell you a highly competitive free market should provide ample opportunities for better employment and wages. Socialist would tell you that such a thing would never happen because society wouldn't do that to itself.
In practice, the real world is messier than that and the existing examples are the US (capitalist), the Soviet Union (socialist), and mixed models (Scandinavian). Granted, they're all "mixed", no country is "purely" one or the other to my knowledge.
