"Our forefathers made these laws because they saw that given the opportunity, entities with a profit motive will pursue profit over all else, to the detriment of society as a whole."
Half of our "forefathers" built fortunes on the backs of slaves. They got plenty of other things right, but many of them missed the mark on racial and gender equality.
I'm guessing that you misread forefathers as "founding fathers", but still, you're giving greater credence to my argument.
In abolishing slavery, lawmakers in 1865 made it clear that regardless of how profitable slavery was for slave-owners, it was bad for mankind and would not be tolerated.
