I agree with you, if we wouldn't have to pay per kilo to dispose off the garbage, I would pick it up myself too. I can't stand to see it. And I really feel that much more people should do that, besides that people have to get more awareness. But yeah, I'm afraid that's also an utopia to think that will ever happen.
There is seriously much wrong in the world these days. And I don't see that change any time soon.
