Well, speaking personally, it is not that I am not inclined to get married, it is simply that I prefer to wait and make a good choice. Or at least a more informed one, based upon experience, rather than accept the first offer that comes along -or 'settle' for someone who is conveniently available.
That's part of what I'm talking about. In the past, once marriage occurred, the wife had a strong incentive to make sure the husband stayed happy with the marriage -- if he walked away, things would get very hard for her. Therefore, her incentive was to get the best (good provider, easy to please) guy she could find within the fairly narrow time-window she had to get married in.
