In this revolutionary exposé, Harvard Law School bankruptcy expert Elizabeth Warren and financial consultant Amelia Tyagi show that today's middle-class parents are increasingly trapped by financial meltdowns. Astonishingly, sending mothers to work has made families more vulnerable to financial disaster than ever before. Today's two-income family earns 75% more money than its single-income counterpart of a generation ago, but has 25% less discretionary income to cover living costs...

It's really interesting. You know how some economists said that in the future we would have shorter and shorter work weeks due to increases in productivity?
