I do feel the marriage sanctity that society once strived for, in the face of people like me, men who miss treated their wives, couples who treated marriage as a contract rather than a union, children who were deprived of love and means, etc. is pretty much over. The eagerness that people have to hand over a custom merely shows how invaluable it is to the community, regardless of the significance it has for past generations and a vast number of extant couples.
One thing I agree with marriage, is it has become a look at me spectacle, followed by a quickie divorce.
Just bring in a 50% of net worth divorce tax. That will clarify the meaning of "For better or for worse".
