Germany during WW2 send many of their most educated people to the frontline because the ultra rightwing government in charge in those days did not like well educated people.
1) it was an ultra leftwing government, never mind what the leftist propaganda of the last 60 years tells you. It's National SOCIALISM. Hitler wrote Mein Kampf while in prison for his involvement in a COMMUNIST revolution in which he was a key figure.
2) they didn't, actually. Educated people were used to great effect to develop advanced weapons and other systems. Without those people you'd not have jet aircraft, computers, space travel, a lot of plastics, etc. etc. today.
