I have not hit the link, but the boomers as a whole have been the "me" generation. It is not surprising that a generation focused on self would have no issues about disposing themselves of marriages since they are a group that grew up in a disposable world. Car problems? Get a new car. Hate the city? Move. Hate your job? Start a new one.
Personally, I really hate the word divorce and the very idea of it makes me sick to my stomach. Yes, I see so many children hurt over divorce and the parents don't care one bit.
