How could it make sense to require people to graduate high school to go to barbering school?

How could it make sense not to offer a shortcut for someone who already knows how to do the job to skip most of the schooling?

How could it be just to impose a heavy fine for barbering without a license, on the first complaint?

How could it be just for a court to issue a fine and not appoint a lawyer to represent the person that might be fined?

My friend Paul sent me this:

It might help understand this if you know that an amazingly high proportion of cosmetology school students are older black guys who have gotten out of prison. Opening a barber shop is one of their few avenues to owning a business and making a living, given that their criminal record makes it almost impossible to get a regular job. So it sounds like Tennessee is trying to put more obstacles in their path.
