Yup. An often-overlooked element of "internships" that are really just entry-level positions is that, especially in expensive urban areas, a serious level of privilege is required to even consider working for free for a year. It restricts these positions to families of a certain class. Intentionally
don't forget entrenching existing networks and wealth, as you have to have -some- means of support to do this [Disclosure: Did an unpaid internship in college. That was also thirty years ago].
