Gain a restaurant, lose a country.
Without slavery America would still exist instead of starting a long death with the 1965 immigration Act being the final nail in the coffin.
There is no “without slavery” regarding the colonization of this continent or the establishment of this nation. Europeans didn’t even introduce the practice, it was already here. We really take too much for granted, human bondage in some form or another is really much more the norm, historically speaking, than is being free citizens of a constitutional republic. We have the luxury of being free of the practice, and labor under the false impression that it was eradicated for all time in 1865.
It wasn’t. There are slaves to this day.
