I've been watching The Americans, which is set in metro-DC (America) in the 1980s.
I noticed that the stars, whose income comes from their jobs as travel agents, live in a home I'd estimate as costing $1M USD in today's money. Their neighbor is an FBI (American Federal police) field officer with a stay at home wife. His house is comparable in value but maybe slightly smaller, perhaps $700 - $800k.
In Season 2 they showed an Air Force Colonel's estate. It was a true mansion. It had to be at least $2 - 5M.
Given the occupations, is this realistic? It very well may be, but I just didn't know that these government positions paid so well (though I realize that there's probably a lot more variation in what travel agents used to make before they became extinct due to the rise of the Internet).
