Assuming franchisees make less margin (which I guess is fair to assume): What does that matter? If the parent company took less margin overall and distributed that ver each franchisee they could pay more. According to a quick Google there are a bit more than 38000 McD restaurants in the world. So still around 500k. I'm not sure what number of people an average McD employs as I'm reading numbers that differ wildly.
