The con is in the DNA of this country, which was founded on the idea that it is good, important, and even noble to see an opportunity to profit and take whatever you can. The story is as old as the first Thanksgiving. Both the con man and his target want to take advantage of a situation; the difference between them is that the con man succeeds. The financial crisis of 2008 was an extended, flamboyant demonstration of the fact that one of the best bids a person can make for financial safety in America is to get really good at exploiting other people. This has always been true, but it is becoming all-encompassing. And it’s a bad lesson to learn the way millennials did—just as we were becoming adults.
