There are numerous studies out there that show UI is not the cause. Posting them is useless as your mind is already made up.
You should post them anyway, for everyone else whose minds aren't made up.
And for the record, I don't think UI alone is the sole culprit. I think it's a combination of UI, PUA, rent/mortgage deferment programs, stimulus money, and free food, together with a whole lot of other smaller handouts. I think that the numbers will speak for themselves once these programs are no longer available. It should be evident first on a state level (with state regs becoming stricter), and then on a national level in the fall/winter. I could be wrong. Predicting things doesn't always go my way.
