One would like to think licensing is about ensuring quality, but if one actually takes a look at the reality, one realizes that licensing is about restricting the field and paying to play, and almost never about ensuring quality.<p>Even professional licenses are like this, unless you are a complete idiot it&#x27;s not the knowledge that&#x27;s the problem (e.g. passing the exam, if there is one), it&#x27;s paying for the requirements (e.g. the degree and&#x2F;or the continuing license fee) or fitting the requirements (e.g. being a foreign worker).
