Well...
The USA was founded on slavery - so one could say that its hypocritical to pretend. Others would say that its better to grow and try to steer things to a morally superior stance at great financial cost.
The abolishment of slavery in the USA is no doubt causing great stress in the middle states of America today. I'd argue that without some form of slavery (human or machine) that the central US states that rely on agriculture will simply revert to the 15,000 year stagnation that happened to the natives that came to America from Russia. As a culture, Russians came to America 15,000 years ago - became Incans, built a couple pyramids - and then mostly stagnated.

I believe this is what Trump wants to avoid at all costs. Something about Mayan/Incan central American culture that caused it to basically die off for a few thousand years.
