>>4922401in the 60's and 70's im pretty sure it was around 88-90% white and 10% black / 2% latino/others
I may have slightly overestimated the numbers but not the basic fact that we were a raically tribal homogenous country with little mixing by that point
the changes since then especially to our culture or atleast our "system culture" have been nothing less then dramatic despite it only being 2-3 decades
