I've seen domestic abuse happen too often in too many kids' households at my high school to think this is a small percentage.
You're assuming it's an intact household, your first mistake. If you look at the rates of male on female abuse (leaving aside the LARGE female on male that mandatory prosecution has undercovered), if husband-fathers are taken out, the rate doesn't change much at all. The VAST majority of perpetrators are the never married, cohabitating, boy-friend, step father etc.
And yes, no fault divorce has been correlated with the decline in the marriage rate. More people are not married now in the US than are married.
Many times, people don't get married for the right reasons, or did not know each other long enough to make an informed decision. Counseling only works when both sides are open to it.
Unilateral divorce has not, nor will it ever, solve any of these problems.
I realize this may be the case with some lawyers, but I was referring to those who wish to be considered good Orthodox Christians. And for them, however small a minority it may be, I would assume that their personal morality would overcome the drive for money.
I don't know, for all the Orthodox lawyers I know, money was a, if not the, factor why they got into it. For some, it was not as crass as it sounds: one switched when he got tired of trying to make ends meet as a nurse, with two children.
