Baby Boomer Age Wave Theory
  
If you didn't already know, a monsoon of crying babies flooded the U.S. and Europe shortly after WWII when soldiers returned home. Since everyone commenced baby-making at the same time, the "Baby Boomer Generation" was born. Because of their size as a generation, Baby Boomers have had a real effect on U.S. and European economies.
There are two main ingredients in the Baby Boomer Age Wave Theory:
1. The generational tidal wave of Baby Boomers is now headed into retirement.
2. Economist and writer Harry Dent found that people spend the most money around age 50.
With all those Boomers looking like P. Diddy with their cash-money, celebrating the big 5-0, Dent concluded that U.S. and European markets would soon be booming. The idea was that the biggest generation dropping the most cash on the economy would result in market peaks. Most Boomers were celebrating their 50th between 2008 and 2012, meaning the economy is now (theoretically) on the downhill slope. But don't hate the players, hate the game. It's WWII's fault, not Grandpa's.
