If we are individualistic, then why do we organize ourselves into communities instead of living as lone wolves?

The truth is that humans are social creatures that prefer the company and support of other humans. The way we spread around the globe as hunter gatherers was through cooperation and mutual support. A lone wolf cannot support themselves if they are hurt, or sick, or lack a skill, or simply didn’t save enough food in hard times. But a community can.

So, I don’t think our nature is individualistic so much as capitalism is individualistic.
