He can't. Any positive result that happened in this economy occurred in spite of Obama policies, not because of them. Serendipity has never been kinder to someone less deserving. He never as much as managed a Lemonade Stand, much less any substantive business enterprise. And, he surrounded himself with people void of any real business experience/successes.
In running for office, and while in office, his rhetoric and verbiage would scare any business owner, large and small, as well as any prospective entrepreneurs. He has promised higher taxes, additional regulations, Cap and trade, Obamacare. Uncertainty has always been the constant in suppressing any economy. BHO has created enough for three administrations.
"Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, it's inherent virtue is the equal sharing of misery"
