You mean it does for you. I have no idea what works for other people. I like Shaw's dictum "We have no more right to consume happiness without producing it than to consume wealth without producing it." and "A lifetime of happiness! No man alive could bear it: it would be hell on earth"

Capitalism is merely a description of people's desire to trade goods and services with each other with as much freedom as is compatible with civil society. It didn't need to be invented; it was a natural occurrence. I do understand that some people would like to prevent that from happening.
