Things are slightly better, yes. We have the market (and to a limited degree-certainly in healthcare, though the jury is still somewhat out on that, Obama) to thank for that. But a mediocre economy over a recession isn't enough to make President Obama a great President.
For example, despite the recession officially "ending" 6.5 years ago, household income is still 2k less than it was in 2007. Likewise, labor force participation rate has declined among EVERY demographic and age group EXCEPT those over 55.
Obama will be the first president in a long, long time to never have a year of 3% GDP growth as well. In fact, as of right now, W has averaged more economic growth than this administration.
You can manipulate stats all you want, but most Americans agree that things are not better. Why do you think a mere 28% of Americans think things are going in the right direction?
Most Americans agree upon a lot of things that aren't quite true.
Tell me, oh wise one, what is the truth since you apparently are the arbitrator of it?
