It'd be great if these optimistic projections are what happens, but today's american culture and economy is still very growth centric - I don't see it happening.

Though note that it really is long-term.. it takes a couple generations for the population to stop increasing after birth rates drop, since the previous generation still contained more children.

The U.S., like Canada, Australia, Brazil, and many Spanish-speaking countries in America, along with the former colonizing countries of Western Europe (e.g. England, Holland, France), is an immigration-based country, and so birth rate is only one factor. Given the number of people from China, India, and elsewhere who would immigrate to the U.S. if they could, it's not inconceivable that one day the U.S. will welcome them and their money so Americans can profit from another residential property Ponzi scheme.
