The only thing wrong with capitalism is the lousy job its so-called defenders do of defending it. Readers are referred to Atlas Shrugged for a comprehensive and cogent defense and explication of its many virtues. From John Stossel at theburningplatform.com:

Presidential candidates and the media keep telling people “it’s immoral” that a few rich people have so much more money than everyone else.
They talk as if it doesn’t matter what the rich did to get the money. Instead, the fact that they are rich is itself immoral.
Yaron Brook of the Ayn Rand Institute says this is lunacy. “They want to condemn the people that actually have moved civilization forward,” Brook complains. “People who improved the standard of living for everybody on the planet.”
