Marriage has failed. Now what? I believe marriage has failed and never worked anyway .......?

Marriage hasn't failed, and its not a construct some 100 years old, its around as long as recorded civilization. What has happened is progressive liberals have realized that reducing your reliance on existing old institutions like church + marriage increases your reliance on government, which increases their power. So they have pursued over the last few hundred years policies that do all they can to break down existing institutions other then government. Its pretty obvious if you look at it - support for vague spirituality but any specific religion is a problem, teaching that the children are more important than the spouse, the whole "do what feels good" movement, etc.
