Question

Over the past century, what factors have caused families to change?

Answer 1

Infiltration of social change-agents in education and politics to debase the trasditional family unit for easier control.

Answer 2

One aspect is that many females have become sexually and occupationally liberated to the point that they tend to exhibit the same behavioral tendencies, both the good and the bad, as males.

As such, we now tend to have family units which are based on complete equality and equity, rather than accepting complementary roles which put a premium on a functional family unit.

The achievement of individual goals becomes the primary emphasis, rather than the preservation of the family unit.

Is this a good thing?  I don't know.  Time will tell.
