Of course there's "no evidence", they didn't even sample an entire category of low-wage employers, counting anyone who got a job in that category as a job lost. That is so obviously flawed, it's laughable, yet you think it's statistically legitimate. You think no data = knowledge. Someone needs to take a refresher statistics course.

Legitimate statistical analysis requires samples from all the known categories of data relevant to the study. It's not just possible that corporations have different policies and hiring strategies than franchise or solo owners, it's pretty much guaranteed.
