Fear in 2009 and Greed in 2015

We have finally moved from fear to greed.  Nobody is worried about recessions.  Builders are building. Contractors are busy, and bids are going up.  Commercial and residential property prices are going up.  Interest rates are low.  To do deals today, you have to either lower your margins or increase risk or bet more on the future than the present.  Up it goes until it blows.
