I do not think so. The sad reality, at least here in USA, is that MOST people get divorced. Reasons for that are beyond the scope of this forum, but the reality is more then 1/2 of all marriages end poorly, so it makes it hard to blame just one industry for it, IMO.
As for the comments about start up business vs self pub, I call BS.

I have done both, and there is no difference. If you want your business to succeed you put insane hours in. It does not matter if you are selling ebooks or widgets. Same time/funding/etc problems apply.
BTW - I am 16 years happily married and plan to stay that way. Anyone can let their job consume them. It is all about setting limits and sticking to them.
