It is also like medicine in that it has a tendency of ending up being worse than the condition it was meant to cure when taken irresponsibly or in too large a dose.
There's another way in which debt resembles medicine: those who sell it are wont to sell it as widely and at as high a price as possible, no matter whether it is the right medicine for the condition at hand.
When used responsibly debt can be a net positive. When allowed to run amok it is a burden upon society. Maybe debt, like medicine, should only be allowed to be taken with a prescription?
