Unemployment is not particularly low. Also employment rate says nothing about the types of jobs available.
The dollar is super low right now. Why is it low? In part because China's yuan is undervalued and making the dollar low helps stave off the loss of manufacturing jobs to China. That also has to do with why interest rates are low. Keep the value of the dollar low, and inflation and interest rates stay low. Those low interest rates are good for certain things like housing and cars (notwithstanding the fact that the automotive industry is in a definite rut at the moment) but not good for people trying to make money on interest rates.
The stock market is also not in an upswing. It is stagnant. Why? The low dollar, low interest rates, and diminished revenues which can only be made up for so much by ever-smaller increases in efficiency.
No real economist would tell you we're in the middle of a boom right now, and that's because we're not. Is the economy falling apart at the seams? No. But it's not that great and the part of it which the government does have direct control over--the federal budget--is out of control.
I for one am not so presumptuous as to think that the health of the economy totally hinges on who is in the oval office. I don't really think it's a good campaign issue. I think federal budget policy is a better one.
