Your "seed corn" argument is not obvious to me, especially since we are talking about corporate taxes. Care to elaborate?
I think one of the unintended effects of the loose monetary policy at home and abroad is the extreme rise in home prices in all major cities. I think most of this was not intended by the policy makers. But investor dollars follow safety and returns - real estate has been an amazing investment since 2008 (look at major cities like Toronto, Vancouver, SF, etc.). We're talking about doubling you capital in less than 10 years. This is not stopping ... I don't think it will until rates go much higher.
