I began reading a New York Times article, "It’s Not So Easy Being Less Rich," on people whose "incomes have shrunk, say, to $2 million/year from $8 million," available here.
It was difficult to read.
The secret, apparently, is to sell things that your rich friends wouldn't notice. Prominent art might get noticed, what with the now open space on your salon wall. But jewelry you rarely wear seems to be a good way to raise $2 million, according to the article.
So there is hope.
