Scott Adams said this quote

“ Capitalism is rotten at every level, and yet it adds up to something extraordinarily useful for society over time. The paradox of capitalism is that adding a bunch of bad-sounding ideas together creates something incredible that is far more good than bad. Capitalism inspires people to work hard, to take reasonable risks, and to create value for customers. On the whole, capitalism channels selfishness in a direction that benefits civilization, not counting a few fat cats who have figured out how to game the system. You have the same paradox with personal energy. If you look at any individual action that boosts your personal energy, it might look like selfishness. Why are you going skiing when you should be working at the homeless shelter, you selfish bastard! My proposition is that organizing your life to optimize your personal energy will add up to something incredible that is more good than bad. ”
