And now we find ourselves at the beginning of the meme.

Also, I find "people are greedy" to be an uncompelling reason to support a system that incentivizes greed and exploitation. If people bending a system to benefit themselves is a problem, then the system should be designed to be resistant to this, in a way that incentivizes promoting the common good. Or at the very least shouldn't encourage these problems.

Capitalism encourages these problems.
