EDIT: I'd like to add that this is mostly US-centric. In other countries, doctors probably range from B tier to S tier. As for defense attorneys, I honestly don't know enough about their demographics to determine how many of them are Alan Dershowitz and how many are actual public servants.
Agree in part, except the public defender system is so badly funded in many places that they essentially work as an arm of the police and force bad plea deals or cooperation with police on their clients simply to get through their overload of cases. This is more a systematic failure and public defenders individually are generally working to do a good thing, but the profession overall isn’t really A-tier in practice
