Honestly? Education. When you learn how the system works, you learn thatthere's really not much you can do about it, and though not guaranteed, the outcome will usually be good in the long run. So, maybe education, and a bit of surrender and hope.
I think using "that's how the system works as a justification is a cop-out answer that is used for justifying some pretty terrible views. None of our ancestors, from those who served under feudal lords, to the people who fought for civil rights for women and minorities, ever fully accepted "the way things are" - if they had, none of us would be as well off today as we are.
Hm, maybe? I wouldn't know. I don't go to Harvard. Just lucky to have gotten into this school (though busted my butt like crazy to get in there). My parents aren't rich, and I'm paying for the $30k a year or so that it costs pretty much entirely out of my own pocket and through loans.
While hard work + out-of-pocket/"bootstraps" stories are inspirational, but they are the exception, not the rule.
If everyone was a winner, no one would be. We either have one very skilled and driver winner with 10 not so skilled and risk adverse employee losers, or we have one somewhat lazy welfare recipient with "needs" as a winner, and 10 people working and payi g taxes as losers. I'm all for equality, I just don't think it will work, since it will naturally degenerate to communism or free-market libertalianism over time. Always has.
I would rather there be no winners and no losers than a few winners and a ton of losers, but I genuinely care for my fellow human beings. I also don't believe in this "lazy welfare recipient" meme; welfare is not some glorious thing. People want to be productive, nobody likes feeling useless. The best solution you can have for this is to offer a bunch of "public works" programs to allow them to take on jobs that make them feel productive while they are in-between full-time public service jobs or private industry careers, Of course there will be freeloaders - that happens, but it is far more better to deal with a few freeloaders than demean ourselves as a species as cast those who cannot get work, are too disabled, or are too depressed to be motivated to the side like trash instead of taking care of them and leaving open opportunities for them to improve themselves.
Finance doesn't actually suck money off labor. It sucks money off debtors and investors. Human resources sucks money off labor. I don't know if human capital management degrees are free-market capitalists.
Likewise i can say the same about you. You didn't learn something that led you into supporting socialist-democratic principles, you just saw that some people had things you didn't, got jealous, and wanting to have what they have succumbed to your greedy nature. Everything in the world is done for selfish greedy reasons, even if the reason is so that you can feel good and smug about yourself.
I'm not jealous at all, I'm reasonably well off, since I was born into a well off family.
Maybe what you could more accurately accuse me of is "feeling guilty". People like you and I have been lucky to have many opportunities available to us. Hell, I haven't even had to pay for my college education. I'm very thankful for all this.
I also know that not everyone in the world, hell, not even in this country has had even close to the chances I have. I am also aware that many of the things I buy, including clothes and even food, are products created or retrieved by slaves. My anger at the "rich" comes from the fact that I know that the ratio of 'labor/work' they do compared to the laborers at the bottom is much different than the ratio of pay they both receive.
Also, finance very much does suck money off labor: it may not be directly; but it still does. It's similar to what I said above. Debtors/investors are actually laborers often, too.
