Social skills, such as communicating and interacting with others, could be lost, along with emotions such as love, sympathy, trust and respect. People would become less able to care for others, or perform in teams.

Is he predicting an increase in the number of conservatives?

Seriously, his physical descriptions of the diverging subspecies seems to rely on some pretty obvious and even discredited stereotypes (tall and graceful, square-jawed, athletic, vs squat, short, brutish knuckle-draggers). His master race sounds like a bunch of olive-skinned Aryan faggots.

No, I think this guy is thinking too much like an Englishman. I see it working out differently.

The underclass will have to struggle to survive, they will take heavy casualties without the advantages of the well-to-do, but natural selection will reward the fittest. The cleverest and toughest, mentally and physically, will survive and pass on their genes to their offspring.

The upper classes already live sheltered lives, and use extraordinary measures to restrict their reproduction so they can accumulate wealth and enjoy their leisure and privilege, and they will lavish all sort of benefits and protection on the young they do have so that natural selection will have very poor material to work with, and little opportunity to cull the herd. And of course, they will only marry into their own class.

Look at the elites today, and compare them with the common folk. There is plenty of evidence that this is already starting to take place. Most of the leadership class in the US today originally came from solid, working class material (usually immigrant stock, the huddled masses of Southern and Eastern Europe). They were subsequently mongrelized, that is, they are genetically more diverse and therefore genetically superior.

The white-bread-and-mayonnaise Yankee upper crust of the Gilded Age were already showing signs of inbreeding and decline in their heyday, not too many of that genotype remain today in positions of inherited power.

As they say, "Class will out." 8)
