AGAIN:
You cherry-picked a 20-month period.

Obama governed for 8 years, most of the first 3 years of which was disastrous. Even when things improved, it seems to me that things hit such rock-bottom that there was nowhere to go but up.

Also, much of the "growth" was actually fake growth and deficit, where Obama racked up 10 trillion in debt in his 8 years, more than all other past presidents combined.
Add to that the over 3 trillion in new currency printed during Obama's term, another way for the government to spend money that it doesn't have. Financial firm owner and CNBC panelist Peter Schiff said that a government printing money is a subtle form of taxation. Instead of directly taking your money, the government just prints trillions more, making every dollar you have in the bank worth less. There was 800 billion in printed currency when Obama took office. And before he even left office, there was over 3 trilliom more in currency printed, which more than quadruples the money supply.

So Obama burned the wick at both ends, and left this country in a far greater financial bind. Using that vast spending and printing of dollars to create the illusion of a growing economy. And even with all that waste, was only able to create 1% to 2% growth a year. At enormous cost. The federal debt was about 40% of annual U.S. GNP when Obama took office. Now it is over 100% of GNP. Trump is rebuilding our industry and our military. Reversing the destruction of Obama.
