The falling gas prices are having an effect on the consumer's mood. But, it will be fairly short term. Layoffs are starting in that industry. With the oil and gas jobs, the economy would be a lot worse as we are still mired in the worst recovery in decades and most of the jobs, save for those oil industry jobs, have been low pay, part time. I wouldn't be surprised if the Fed starts hinting at more Qe if current trends continue.
I haven't heard this on the mainstream news yet but Bloomberg’s had an article last week were 30 year Treasury yields fell to a record low. This is getting to be 2007ish when GWB also talked up the economy in his 2007 SOTU speech
Also, the employer mandate just went into effect this year.
