I don&#x27;t have a problem with that. Anything with healthcare or safety (electricians, plumbers, gas installers, builders, car mechanics) must be regulated in order to protect the public.<p>90% of the skill required in many jobs can be learned in a week or a month. It&#x27;s the 10% you only learn over the course of education that are safety critical, though. Not to mention practicing in a safe environment instead on your customers or their homes.<p>Let&#x27;s take your barber as an example, and only the stuff that comes to my non-professional mind:<p>- highly aggressive chemicals that will ruin your health if you&#x27;re not taking proper safety precautions<p>- the fact that you&#x27;re meddling with a deadly sharp knife at the necks of your customers<p>- health hazards for the customers: lice, other transmittable diseases, improperly disinfected equipment<p>- health hazards for yourself that can be carried by your customers and you can pick them up (e.g. you cut the customer by accident, he&#x27;s HIV+ and you have an open wound on one of your fingers while not wearing gloves - something I rarely see barbers do)<p>The fact that the IT industry largely consists of self-educated people might be pretty cool but on the other side, how many security incidents could have been avoided by proper education? Even for BASIC security like not doing echo $_GET[&quot;name&quot;]?
