1) I worked in the Family Court for a year -- it's definitely not draconian and broken to men. As I said in another post -- it is only in rare occasions, like habitual drug use (not just alcoholism) that either parent loses custody on divorce, and in such cases, the woman was just as likely to lose custody to the father.

2) The divorce rate has been going down steadily, despite the lack of change in divorce laws -- the rise in divorce was a social phenomenon, not a legal effect. Less harsh laws might have some effect, but not the level of impact you're thinking.

So that would be a categorical no to the first, and a qualified yes to the second.
