technical debt is actually worst than financial debt. imagine an interest rate of x%. now imagine that one day the bank comes in and says: now your interest rate is going to be 20x. you don't get a say in it and you cannot refinance.

also another mistake I've seen made over and over again is to say stupidity==technical debt. If you're doing stupid things just to 'get things done' you're doomed in the long run. If you've thought about it and made the decision to cut a corner you should know why you've done it.
