Yes, the adversarial legal system means there is a balance of power on both sides... on paper. The law tends to serve the rich and socially significant people better no matter which side of the court they are on!
The defendant is "too bright" to go to prison for stabbing her boyfriend: Not even the judge cares about the law!
https://www.telegraph.co.uk/news/2017/09/25/oxford-student-judge-suggested-bright-prison-spared-jail-stabbing/Yes, many jobs don't do good to society. But adorning such a, as you have said, potentially offensive profession that is law with such prestige (far above trash collectors) is the problem here. People who have talent in, say, Biology, who could possibly one day invent a cure to previously incurable diseases, might end up choosing Law over Biology because Law sounds more prestigious to him, and that is a huge loss to the society
Law is far from the only profession requiring paperwork, but for a subject that is already boring at university level, coupled with the extreme stress that is probably not seen in teachers, it is a recipe for disaster all along don't you think?
I actually found a few law modules interesting, but looking at statutes of those subjects is probably the least interesting part thereof... really! The case law is probably what you are looking for.
I do regret studying law even as the humanities-nerd that I am, not that I did not get A's in science subjects. Also, the paths available to humanities students tend to also be available to.. science students! But not the vice versa! In this aspect, law is even more contentious, as people from any degree subject can convert to law in 1 year's time.
As for humanities students converting to science subjects, you'll probably have to retake A-levels if you did not already choose science subjects AND start over again from scratch all 4-5 years of a science degree.
That is simply unfair
