You guys are right to say a medical or law master degree is so different than a CPL/IR.
The CPL/IR: you are in a cokpit or not. That's a driver licence associated with a medical. The only goal is the cokpit, final point. Like the bus driver licence is to drive a bus. A CPL/IR doesn't even make you smarter.
A Law master degree however changes your brain and leads to many fields: Civil servant, Lawyer, manager in a company... hell if you don't find anything you can stay at home and set a website to give law advices. Hard to use your CPL/IR at home... We really cannot compare both training, a law degree is much more flexible. A CPL/IR looks much more like a lottery ticket than a proper education.
