If you could only change one, would you have better wages for lower paid, or more access to trains and career paths that create social mobility?

Edit… A couple things are important here. I am not talking about capitalism. It's really more of a theory question. I have a moral dilemma. The second thing is why I'm asking a theory question is that, I see a path in a major company to create long term growth for a lot of people. It would come at the expense of short term income. I don't agree with it but we are where we are and maybe if I address long term, later I can fix short. But for now this is where I am.
