Parent isn't speaking about just qualifications, but the extent to which the government also controls supply of healthcare professions in the US, largely via its residency funding, and requirements to complete a residency program to practice (to simplify the system to a sentence). https://www.nationalreview.com/2021/10/america-cant-fix-its-doctor-shortage-without-fixing-federal-financing/ https://www.nationalreview.com/2021/10/america-cant-fix-its-... So it's generally accurate to say "You cannot be a physician in the United States without the federal government's permission." (At minimum, indirectly via position funding) And since we generally require a credentialed physician at some point for most care, that trickles down the entire system.
