We would all be better off if our immigration system didn't create a process where some bodyshop pimp gets to skim 50-80% of the billing!

When my grandparents immigrated here, they did scutwork for low pay, but at least they got to work for their employer. There wasn't some layer of middlemen skimming the cream.

This is true, but when an entire society does this, then all it does is exploit cheap labor and leads to a race to the bottom to see who can charge the least, all while the capital owners reap the rewards.
