actually, capitalism 101 teaches that "making more money" and "better for the consumer" are synonymous so long as markets are competitive and operate at the market clearing price, that point which is also best for the producer.

In theory communism also works.

i don't have time to write a treatise, but if we consider capitalism vs socialism/communism to be equivalent to quantum theory vs general relativity, that part of communism (allocation of resources) does not in theory work.
