@dashrandom assume? No. I’m emphatic about it!
Yes, capitalism is default human behavior, and we can see that evidenced around us every single day.
Heck, at the moment you’re investing time typing your message. You’re spending resources on that project in hopes of some return on your investment in time, typing into some device that you invested into in the past, all with trade involved, all looking for increased value to come out in the end.
You’ve invested your capital in hopes of future gain.
That’s capitalism for you, the default human behavior.
Did you ask permission to write your comment? Were you forced to make it? Unlikely. And yet, even such force would be overriding the capitalistic default.
