Apparently you don't understand the statistics. No, the Labor Participation Rate is not the lowest under Obama since the 1950s. Please go to the charts and correct yourself. It declined only 2.9 percentage points under Obama, and was ALWAYS higher than at any time prior to 1977. Since charting the figure in 1948, the LPR was always lower than it was under Obama until 1977. It peaked under Clinton and started declining under Bush.

It is unrelated to the unemployment rate. If you're going to engage with me in substantive civil discussion, you need to learn what these figures are and stop trying simply to score rhetorical points. That doesn't come off well when you misread the numbers in the first place.
