Post-crash, the US economy has been limping along for nearly five years despite a series of massive fiscal and monetary stimuli. A principal reason for what growth we have had is the spending pattern of rich people, who tend to put off their big purchases years later in life than the average. Their peak spending year should be, according to Dent, 2014.

And, no, immigration isn’t going to save us; even adjusted for immigration, the overall US population is aging. (Moreover, an anemic economy attracts fewer foreigners: Net new immigration from Mexico dropped to zero between 2005 and 2010).

Lost in the discussion of this week’s Congressional Budget Office report (which said 2.5 million fewer Americans would be working because of Obamacare) was its prediction that aging will be a major drag on growth: “Beyond 2017,” said the report, “CBO expects that economic growth will diminish to a pace that is well below the average seen over the past several decades [due in large part to] slower growth in the labor force because of the aging of the population.”

Economically speaking, winter is nowhere near an end. Spring isn’t due until about 2019, which is when the economy will receive a boost from the spending power of the Echo Baby Boom of the 1980s (which peaked in 1990) and the concurrent wave of immigration. In 2019, these second Baby Boomers will buying their first houses.
