The magical device on which you're reading this comment would not have been possible without companies employing people they thought would help make the company richer. It's not a zero-sum game; we all benefit as a consequence of capitalism – from the richest of the rich to the poorest of the poor.
Have you ever owned a business or hired someone? If so, did you deliberately select employees who would not help the company be successful, and if so, did that somehow help prevent societal collapse?
I hear so many lies about the "evils" of capitalism (from all sources, not just here); I fear people are starting to believe them, as we're slowly being brainwashed into joining the next reboot of "let's see – again – how badly we can screw up the world with communism".
