Same analogy applies to individual people. Imagine a friend of yours who has a bunch of debt, is having trouble earning enough money, and just took on a bunch more debt for some new ventures which he hopes will pay it all back.
Most people would tell their friend the prudent thing to do is spend less money for a bit, pay down your debt until you get back on your feet. Not open up some new credit cards.
This is probably why people have trouble understanding the "go into more debt to get out of debt" approach.
