People do this because of the economics of the system. We can't fix that by focusing on morals (because morals can be manipulated as @dinofelis and others have pointed out). We can only fix it (if at all) by embracing a holistic economic model change. I posit the gift culture coming in the post-scarcity knowledge age. See what I wrote about a deflationary currency and follow the links in that post as well. I don't think you are really getting it. I feel I write and people don't really get it.

We can't fight with social justice activism (that is the mistake of the younger generation). My strong suggestion is to stop that (although you can do whatever you want of course). It makes you a pawn. Its okay to share that music as a motivation (or even at a rally just for the celebration or a party), but we have to actually accomplish a change in the economic model. If we just march on the street shouting morals, then we will be manipulated and defeated. Don't get me wrong. I love that song. I am all for a symbolic activism as a form of celebration or party but only if we know we are winning because of our economic model, not because of our activism. I don't like to lose.
