Ah. Difficult to draw concrete conclusions about "licensing unfairly harms poor people" if e.g. Texas requires barbers simply notify them that they're barbering and California requires that they take a 4-year college program prior to barbering, but it's still useful as an approximation I'm sure.

Interesting how Louisiana (and a lot of other southern states) rank so highly, as I don't really imagine them as being big on government regulation. I wonder if maybe that is a result of old regulations that were once used to keep out specific groups of people.

Very interesting. There are a few professions there which surprised me by only requiring licenses in a few states (Security Guard? Bartender?) and others that surprised me in that they needed a license at all (Florist lol).

I wonder what classifies as a "license" in the first place. Is a brief course proving you can competently serve (i.e. not over-serve) alcohol a "license" to a bartender? Because we have a brief test in my province in Canada for anyone who will work with alcohol, but I'm not sure I'd classify it as a "license", but at the same time you can't do the job without it.
