many people including myself believe that availability of legal services is broadly lacking in the US. not necessarily a shortage of attorneys, but a shortage of attorneys that can do work for anything but top-quintile clients. artificially restricting who is and isn't allowed to perform certain jobs often has that sort of effect.

Not GP, but I never thought of this side effect before. Thank you for making me aware of it!

attorneys multiply when left to their own devices, which is often bad for society.. (since like law enforcement and middle management, LOTS of new people every year want the job for all the wrong reasons) so California Bar limits the new attorneys, which both lessens the total number of attorneys, and also advantages the incumbents.
