Part of the problem is the conflict between conservative and liberal values. Conservatives strongly support family values and maintaining traditional family structures. Liberals want to explore new ideas and different ways of living life.
Exploring different things is great for improving life. However, anything new needs to be assessed against the status quo. If it is an improvement, it should be pursued; if it is not, then it shouldn't be. There does not seem to be a good alternative to family. However, the family structure could be changed and still serve its main purposes.
