Corporations love regulations. That way, whatever happens is the regulatory agency’s fault, and the corporation can claim that it was in compliance with everything it was supposed to do.
The main reason corporations love regulations is because it prevents new business from entering the field and competing with them. The bar to entry is set so high that the expense of jumping over that hurdle is often prohibitive.
It doesn’t have to just be a corporation. In most states, in order to cut hair, you have to have 1200-1600 hours of training. This costs anywhere from $6500 to $20,000. This is more training than most EMTs are required to have. Do you think it’s because cutting hair takes greater skill or is more important? I don’t. I think it’s to keep Joe Schmoe or Jane Doe from opening a barber shop or salon in their basement and putting the chains or the posh salons out of business.
