Younger Americans, especially those between 29 and 37 are seeing their wealth decrease in ways that are a bit alarming for our society:

Despite the Great Recession and slow recovery, the American dream of working hard, saving more, and becoming wealthier than one's parents holds true for many. Unless you're under 40. Stagnant wages, diminishing job opportunities, and lost home values may be painting a vastly different future for Gen X and Gen Y. Today's political discussions often focus on preserving the wealth and benefits of older Americans and the baby boomers. Often lost in this debate is attention to younger generations whose wealth losses, or lack of long-term gains, have been even greater.
