This is about policy for a group of nearly 600k people. If there were no 'racket' I think that most people who want to cut hair are capable of stylish and reliable - above the Great Clips standard.
"No regulation" could increase the labor pool a factor of 10x, given the propensity for these businesses to be 100% small $ transactions.
[Editted in response to your edit] Every industry should have competition, but the national average for hair-cuts is near minimum wage. WTF are you smoking? Do you really believe if the minimum was gone there's a chance "fair pricing not controlled by syndicates" would be just above minimum wage? Is the govt minimum wage a "pricing controlled by syndicates"?
