It's so weird. Life went from so boring and predictable to 'may you live in interesting times' [1] in like 10 years. 2013 feels like a century ago, not a decade. In some ways it makes one have some degree of empathy for what those living around the turn of the 20th century might have felt. There's no way they could have known the ride they were about to step onto, especially as they started off living through the advent of the automobile, dramatic improvements in labor conditions, etc..

The problem with QE is it drove up the price of land/housing as I think a lot of it ended up as mortgage loans. Rents rise with land price increases which affects businesses. It would've been better if the QE had gone to business loans not mortgages. But home ownership trumps more businesses when it comes to getting votes so no govt official is going to make a stink if too many loans go out to land asset acquisition vs creating small businesses.
