The taxing of credentials is an interesting concept I haven't heard before. What do you think some potentially unintended consequences be?
It made me think of the way some professional licenses work. The payment to keep the credential is essentially a tax. Some employers won't list the credential on a job description because then they'd be required to pay for it. But they only hire people with said credential, essentially shifting the tax on the individual and creating a kind of shadow job hiring process where the people being turned away may not be sure that getting the credential would open the door for them.
