Too much soy in the diet?
BTW, your screen name reminds me of the old joke:
"Why are Texans always smiling?"

Too expensive to raise children.

Housing is outrageously expensive and no one gets very much of it.
High taxes, government control, business control (their free market is not our idea of free market) -- too many penalties for growth and investment; too many expenses for families.
