No one marries middle aged men. Well... that's hyperbole. Historically, most men would marry in their 20s. This article says that middle aged men have given up working. Those some men could have been ambitious (or ambitious enough) 20 somethings who -- due to cultural changes -- never quite married and settled down.
That is to say, it is not entirely clear that an apathy problem among old men is the cause of declining marriage rates, given that most people marry well before the age of the men in the article.
