You make a good point, but literally every fast food place near me has a 'Help Wanted' advertisement posted these days. I have the sense that they take anyone they can get, whereas in an industrializing society, the competition for those types of jobs (for recent agrarian -> city immigrants) would be pretty fierce. Unemployment rate might be a better metric, but 'employment rate at food employee level or higher' would be the best I guess.
