Industrial robots exist today. Look at, for example, pick and place machines used in electronic manufacturing.

Look at this teeny tiny little pick and place machine. ( It can place 500 components a minute.)

Or at this slightly bigger setup:

These still need staff to run. You need staff to program the machines; you need staff to load components; you need staff to move the product around; you need staff to maintain the machines.

And then you need staff to do the things that your robots can't yet do.

I have no idea how much someone would get paid for that in US, but I know it's a lot less in Poland / India / China / etc.
