It's a large enough disparity that it says something useful about the component majors. And unsurprisingly, when you look at the component majors, the same effect is dramatically apparent. It's like looking at "total household debt". It encompasses a massive amount of things, from mortgages to student loans to credit cards, from people with 100x assets/debt to people with negative net worth. But it's still possible to look at the aggregate figure and understand something rough about the magnitude of indebtedness in the country.
