I think one aspect that you have overlooked is that there is a reason why companies are paying that amount for that role and that reason is - they (the employee) are expected to produce x amount of 'stuff' at a certain level because it is needed for the company to function.

A boss can't go 'Well, we are only paying person y a third of what we would normally pay so that deadline can be extended by 3x'. Even if they opted to employ a total of 3x minimum wagers that does not equal 3x ability nor 3x the output.

In short - All that you would be doing is experiencing the same pressures of deadlines and performance reviews as your peers for a fraction of what your colleagues are earning but with all the same pressures.
