The Fed looks like they're going to screw things up again. Unemployment is at multi-generation lows. They should be perfectly happy with the Japan-style steady state of low rates, low inflation, low unemployment and low growth, and take this opportunity to purge the system of some speculative risk.
Instead they seem determined to turbo-charge a fundamentally justified secular markup in asset prices into a full-blown bubble, exactly as happened in the late 1990s.
