Indeed!
From fiction and movies, one would think that selling the country's secrets to foreign governments would lead to wealth enough to set you up for life on a private island. Yet when the accounts of the treachery emerge at trial, it's always troves of highly classified documents for a few thousand dollars here or there, maybe a few $100k over decades of espionage.
It still just stuns me every time I read how in reality, while honest people would die before selling out their country, some people will sell out everyone so cheaply.
