The Soviet Union can hardly be described as rewarding rural supporters. The good farmers were declared "kulaks" and dispossessed. Universal education was necessary for universal propaganda. Health care was distributed by social class (in many ways it was preferable to be an academic than a worker because the Academy of Sciences took care of its own.) 
 
On top of this were the mass murder of millions, both educated and peasants. Human capital that gets turned into fertilizer is worth fertilizer.

Some time ago I read a report in a Turkish site that a Turkish geneticist had shown that the Belgians were members of a Turkish tribe. How they had battled their way all across Europe was unknown. Of course, he forgot that the Ankara area was the center of Galatia (as in Paul's Letter to the Galatians)and that Galatia meant Little Gaul and that their ancestors had come from Gaul before the Roman period. And of course, the Belgae were a Gaulish tribe. The sample sizes here are ridiculously small. Go to www.kirkpinar.jp and take a look at the most prominent Turkish Pehlevans (olive oil wrestlers) and figure out where their ancestors came from (some look Greek, some look English and Irish, French, German, one looks like Abraham Lincoln.)
