My prediction of the future:
1) Baby boomers will soon die off resulting in the old "muscle" car market to go to shit. Old POS cars from the 50s and 60s that were once considered to be worth $100K+ will become near worthless. Drum brakes, 120hp 12L V8's and bias ply tires are not cool people. It will also impact Harley Davidson.
2) Hipsters will die off because tofu, starbucks and PBR doesn't provide enough nutrition. That will have a catastrophic impact on Apple, American Apparel and 30 seconds to mars. PBR will continue it's existence purely on the redneck population.
