75% of Gen Xers have higher incomes than their parents

Pretty much what the title says. Though 75% of Gen Xers have higher family income than their parents did (at the same age), only 36% have more wealth. GenXers have six times as much debt on average which seems to be the main difference. Pretty good indicator that there is room for most people to cut consumption and increase savings.

What if increased savings leads to lower money flow and decreased wages?
