"A fool and his money are soon parted"

Of all the bizarre things I've ever run across on the internet, a neo-Nazi, anti-immgirant website in the U.S. has to take the cake. Besides the usual craziness, it has a Spanish language section (for those immigrants they hate?). The Nazis are also supporting a presidential candidate and ... in the U.S., that means asking people to donate money to his campaign. I wanted to write a small piece about this, and wanted to use the common English expression, "A fool and his money are soon parted" in Spanish.

I can say it in formal, schoolbook Spanish, but is there a nice, idiomatic way of saying this?

Thomas Tusser might say that the best Nazis ARE Spanish speaking?

PM palindroma, Rich. If anyone will know, particularly in Mexican Spanish, she will. Ask her to respond on the forum, though, I'd bet a bunch of us would like to know the answer to that question.
