At some point in the not too distant future, the USA is going to start looking like Japan. Birthrates are falling dramatically. Immigration can only make up some of the lack of people having children. On top of that, fertility rates are plummeting due to work stress and pollution. What you end up with is a dystopian mess straight out of "Children of Men". The US government will have to respond if they want to continue to grow and prosper and get people to have more babies. But growth at all costs isn't always what it's cracked up to be. The key is to have more babies but have the support network in place... which never seems to be a priority because women do most of the child rearing.
