I believe the "great heights" you refer to miight be an exaggeration. Job growth never reached a high level during his term in office. He was handed very low unemployment levels, 3.4%, and was never able to achieve the levels of unemployment attained before his inauguration. It also should be remembered that he led us out of one recession and into another. Regarding the Dow, you are correct that it reached a new high in 2007, more than 6 years from its previous high in 2000. That slow pace, 20% over almost 7 years, barely covering inflation, was the reason that Social Security privatization proposals have died a quiet death. I never banked a "misery index" so I haven't paid much attention to it, I don't know how its numbers are reached, but I like to say that Bill Gates, Warren Buffett, and I are worth more than $10 billion each. No misery there, particularly when the rich are getting richer and everyone else's fiscal condtion is stagnant or worse.
And then there's the economic condition of the country on 1/20/09, and those are not by any means the only problems this country faced on that date.
