The article points out no statistical difference has been found in performance or longevity in the job once hired.
The economy of the last few years has put a lot of very qualified people out of full time jobs with companies. Unfortunately the HR departments exercising such bias has exacerbated the problem. Add to this the unfortunate situation of being a white male over 50 and your doomed - so just have to find a way to be self employed. And that is not an easy proposition.
And I’m calling BS on that stat, and pointing out that the article was written with an obvious agenda. I challenge you to find a single biz owner or manager (tiny companies notwithstanding) who will agree with those findings.
I'm working on it.
