Supply/demand, my friend. Less cheap labor, higher wages, work suddenly appeals to Americans.
Supply/demand again. More people, higher housing costs, people postpone marriage and wives put in more time at work, less time having babies.
Whites seem to react to diversity stress by retreating to the suburbs or private school and having fewer babies.
So just maybe, immigration contributes to Americans declining birth rates, rather than being our salvation.
In 1970, our country was around 90% White with 225 Million people yet our birth rate was around 1.5-1.6 per woman.
well said
