Somewhat. For the first probably 7 years those rates are all that kept anyone from buying anything and a lot of the debt was something nobody could avoid like student loans or paying your bills with credit cards and working off all the interest. 
  
 I'd say it's been the past 3 or maybe 4 years that America's started getting stupid with its money again. See the completely irrational rise in real estate prices.

I wonder if low un employment plays a roll in this as well .. So much positive sentiment in the employment numbers I wonder if people seeing these kinds of things makes them comfortable to spend more .  . I've never had serious credit card debt in my business or personal life I've always had enough cash on hand to pay it back immediately . I only use it as a perk to get cashback .
