What has Obama done to create this wonderful job growth?
Any specifics?
He and Jack Lew, former Chief of Staff and current Secretary of the Treasury and the chief architect of Obama's economic policies, have basically followed their introductory macroeconomics textbook.
Modern economic theory rests on a graph known as the "Aggregate Demand, Aggregate Supply" graph which shows that by increasing Aggregate Demand, that is the sum of all consumption, government spending, net exports, and private investment, GDP and employment will increase. So, Obama and Lew enacted several policies to raise each of these factors.
First, the Federal Reserve bought bonds from the private market, thereby increasing the supply of liquid money in the economy. This reduced the interest rate down to the lowest its been in years. This made it easier for businesses, especially small businesses and recent start-ups, to get loans through a series of complex financial mechanisms. This stimulated private investment which helped create the jobs.
Additionally, he enacted his famous (or infamous depending on your perspective) 2009 stimulus plan which boost government spending, which created some public (mostly temporary construction) jobs. But in addition, the stimulus plan also made use of a concept known as the "Circular Flow of Money" which basically says that money goes in a circle and so Obama giving a temporary construction job to some unemployed person creates that job and several others because the additional money that person now has goes back into the economy and stimulates growth, hence why its called a stimulus plan. In short, the stimulus plan both directly and indirectly created jobs (increased Aggregate Demand) by increasing government spending and indirectly increasing consumption.
But, conservatives are quick to point out that he raised taxes and that that hurt the economy, but that's not entirely true. Raising taxes hurt consumption, but it allowed Obama to somewhat pay for the stimulus plan and other bills. And due to several economic concepts which I will not get into (if you're curious look up "How marginal propensity to consume affects expansionary fiscal policy" and I'm sure an an answer will come up), boosting government spending creates more jobs that raising taxes kills.
That's basically it, but in the spirt of balance and fairness, I suppose I should point out that the statistic about the number of jobs that Obama created is a poor indicator about the successfulness of his policies because the vast majority of those jobs are part time and many people are still
underemployed.
