The dirty little secret that most cons like sully won't admit to is that our population's fertility rate in the United States estimated for 2014 is 1.86 children per woman, which is below the replacement fertility rate of approximately 2.1.

However, U.S. population growth is among the highest in industrialized countries, because the differences in fertility rates are less than the differences in immigration levels, which are higher in the U.S.

Bottom line is, to get higher economic growth in the U.S., we need higher levels of immigration. Don't think Sully and his Con buddies are going to jump on that band wagon.
