To what degree can the higher-than-historical-norms in the US divorce rate among Baby Boomers be attributed to unplanned marriages made by guys trying to be deferred from being drafted and sent to Viet Nam?

A couple of points -

- Back in the early 1960s, and continuing to the middle of the Johnson administration, a guy could be deferred from the draft by being married. (Kennedy opened the loophole; Johnson closed it)

- As a result, some percentage of marriages took place expressly for the purpose of deferring the man from being drafted and serving in the Army. (Some folks went to Canada, others got married)

- My assumption is that some (not all) of these marriages weren’t necessarily built on undying love, but more likely on the rules of the Selective Service Admin.

- Divorce rates historically were in the 22–25% range, but by the end of the 70s (and continuing now) they are hovering around 50 %. one of many links

Is this coincidence, or cause and effect?
