Pyramid of Capitalist System

The illustrator could have made more of a point about quite how exponentially wider each lower layer of the pyramid is compared to the layers above.

Except the same is true for non capitalist systems so it would not have been relevant. In socialism the poor are even more numerous compared to the favored few from the party in power.

Inequality is not a capitalism only issue.

I love how people who support capitalism always draw it in opposition to dictatorial socialism, implying that the democratic socialism we see in many European countries is impossible to achieve or non-existent.

It's one of the most simple logical fallacies -- the strawman. Everyone should have learned about this in high school at the latest, yet there are plenty of very smart people on HN touting this viewpoint. It's sad, really, how people lie to themselves in an attempt to convince themselves they are morally superior.
