The economic disaster is precisely why there was so much opportunity for growth. The Dow was at 6,500 in March of 2009. I can find someone at Kroger that could have achieved 3% GDP with those starting parameters. You understand, the economy is like a rubber band, right? You stretch it one way and it always eventually comes back. I hope you understand that.
I noticed you didn't address the whole 'printing 2 trillion' or training wheel interest rates. If John McCain had those numbers, you might see it differently, I'm guessing. Economy-wise, Trump will compare to Clinton and Reagan when all is said and done. Obama was a naive amateur, at best...ask a business owner/your boss, etc.
In summation, averaging only 2.1% GDP growth while deficit spending 9 trillion, unprecedented training wheel interest rates, 2 trillion QE, is hapless by any metric...well, unless you're a complete shill.
