And, unlike labor with payroll tax, you don't pay special supplemental taxes on automation rental.
Although I should at least point out that while true now, there’s nothing inherent to robots that insulates them from this. Tax policy is a human choice, so while not paying payroll taxes is an advantage for hiring a robot over a person today, that doesn’t stop human governments from enacting robot taxes.
If automation really takes off and entire factories can be run by a handful of people it might make sense to move them to whatever low-tax country with a port. Pay the 5 employees running it extra to fly in there for a few months a year each (like oil workers) and if it's in a lawless region add some automatic turrets that shoot at anything unauthorized entering the perimeter. Makes sense as long as extra pay+extra shipping+ammo costs is less than the hypothetical robot taxes.
