There are higher expectations now and more options. The social pressure to marry doesn’t exist as it did through the seventies.
I would not say “it doesn’t exist as it did through the Seventies”, because the truth is, it doesn’t exist as it did through thousands of years of human existence.
The expectations and options are exactly what the Left wants people to see rather than the things that really count such as family.
The reason is, once they have convinced people to chase those “expectations and options” and destroyed the family, they can easily remove the “expectations and options” and all that is left for those people is The Party with no outside distractions from “expectations and options” or...family.
