We are about to be swept up in a wave of automation that in the near to medium term could displace 30-40% of the workforce. The way I see it, half of the black population is unemployable right now. Imagine in 5 to 10 years, 70% of blacks and 25% of whites displaced from the workforce. What are we supposed to do with millions and millions of unskilled and often illiterate mexicans? Think Baltimore is bad? Just wait.
Poor immigrants who came to this country 10 or 20 years ago are still on welfare. Open borders + welfare state = bankruptcy.
