Does anyone else find this chart shocking?

Here’s the source. I was looking up the proportion of part-time versus full-time workers to see if the passage of ObamaCare had any noticeable impact.

(Note: Be sure to look carefully at the left and right axes. It’s not that the whole composition of the workforce has flipped.)

I don’t think you can pin the blame on ObamaCare in isolation (it passed in March 2010), but the so-called Great Recession has been qualitatively worse than the dot-com bust. My short explanation is that the combination of economic turmoil and “regime uncertainty” in general (not just ObamaCare) has made employers very reluctant to commit to a full-time hire.
