Did I say "uneducated"? I was talking about a lack of capital! (Note that education is a form of capital, but I was more talking about the ability to buy tools.)
So? Why do we care if people who are willing and able to do productive work have the ability to buy their own tools? Is this reason to turn them away at the border? Just let people share their tools, it's not rocket science! You're framing these as intractable facts of the universe, but they are conscious societal choices.
Have you never seen the inside of a factory!?
Two workers share their tools, they accomplish little more than one worker would have.
