Which fields have artificial gatekeeping? Do you have any examples? I'm not familiar with the term and couldn't find it online...
u/stcredzero's example is also a great one, as over-regulation is a massive problem. However, it's not as much of an issue for higher paying jobs, which I think are more relevant when we're discussing high-end software engineers.
Note: I'm discussing over-regulation. There's a very strong case for heart surgeons to be highly regulated. There's a weaker case for having strict regulations for hairdressers.
Massage Therapy is one. This varies state to state in the US, but you have to have a license.
