[Iron Man 2] If Ivan Vanko is such a hot engineer that he can make his own Whiplash suit, then why does his dad die in squalor? Why didn't he get rich on his own merits?

Dad was a turncoat SHIELD scientist who defected to the USSR by stealing the Arc reactor plans Howard Stark reverse-engineered from studying the Tesseract. Vanko Sr. promised the Soviets that they would be able to use arc reactor to power their weapon systems similar to what Hydra did with the Tessarract in WWII. Unfortunately, like Howard Stark discovered, the smallest Vanko Sr. able to go for the Arc reactor is the size of a large warehouse, larger than the Akula submarine's own nuclear reactor and a smaller energy output to boot. 

Soviet command was furious. In addition to Soviet politics, Vanko was charged as an enemy of the State and sent off to the Siberian Gulags until the fall of the Soviet Union. Vanko came out a broken bitter alcoholic, and directed most of his anger and frustration on his wife and son.
