Actually, that's not true. Don't forget, interest is income to the one receiving it, and ALL interest, including cars, credit cards, etc. used to be deductible. I'll grant you that made more sense than the way it is now, but I disagree that interest in general shouldn't be deductible unless receipt of interest is non-taxable.
