To be fair, the shopping cart thing is largely a problem in America where we've been conditioned to believe everyone takes care of themselves first and foremost. Compassion can be taught, but it'd take a lot longer than we have in the US before everything goes to shit. If we took the leashes off of the American population right now, we'd have maybe 40% of the people acting like the bottom picture, while the rest would quickly decimate everything trying to take as much for themselves as possible, resulting in the top picture. They're not exclusive scenarios.
