I think you’ve gone completely off the rails here. You said everyone should be free to just do the job they want. I pointed out that perhaps what people want to do wouldn’t match up with what actually needs to be done. You started banging on about squirrels rather than admit that what I said is actually probably the case.
I’ve never denied humans aren’t in intense competition with each other. I just don’t think it’s relevant to point to squirrels as an example of how humans should work, they clearly are very different from us.
