Licensing is simply a control & revenue generating system, that usually does not serve any other purpose.
Many times you obtain certifications through hard work & money spent for training… then the Government wants a fee to allow you to do whatever you were trained to do. Then, the Government can revoke your ability to do those same things, for many times arbitrary reasons.
Having to pay fees every year for those licenses to the Government, when the only thing they do for that fee is… make sure you have a license.
I agree there should be training and possibly retraining requirements, which we already have… but licensing is redundant & only benefits Government.
