First off, Mr. Nickles, ease the rudeness. 
To the issue:
Indeed, with both Bush and Obama, the rate of employment has fallen, though more so during the Obama years. Is this a continuing effect of trade agreements, electronic industry efficiencies, robotization, an extremely strong dollar horse-collaring exports? Or is it masses of older folks deciding to retire, early: cashing out to take advantage of the stock market? The boomer retiring-age worker is the age-related rat traveling through the snake of employment. 
Your "objectivity": I specifically said "number" not "rate" in regards to workers. As can be seen, this has continued to rise under Obama, though the percentage, indeed, has not.

Considering the data, what jumps out is uniformity: whence the female impact? And, economics isn't conducted in a vacuum: what of other leading economies, i.e. Europe, Scandinavia--- how has their employment fared?
