An interview with a communist mayor on Spain.  While hilarious, the video shows the merits of small scale communism, which is simply a small function of cooperation within a broader capitalist world.

The house they tour is only 15€ per month and is private property of the inhabitants.

The point is that what people think of as communism/socialism works well on a small scale because it is akin to a well run capitalist company and subject to the same immutable economic laws that everyone is.

Communism/socialism breaks down on a large scale when it trys to operate outside of these laws.

Enjoy!
