As long as the free market solves the problem, I'm a happy chap.
I guess it depends on how you define "solves the problem". I happen to think they are chasing a dream. A dream that they can still have some imagined traditional marriage where men ruled the home and women were obedient concubines. And they find women on those sites who think they will be better off with these men in America than they would be with similar men in their own culture.
But make no mistake. Those women don't want what American men have. They want what American ~women~ have.
