I don't know why you think that health care fields are immune to cyclical job markets. I've linked an article for you that sounds eerily similar to today.
" Like other job markets, that in radiology tends to fluctuate cyclically. The market is currently very favorable for those seeking a position. In 1988, in the estimation of the radiologists surveyed, the demand in private practice was increasing, and radiology group practices had begun to hire more graduates. By 1994, there were fewer vacancies in the job market, and in 1995 the hiring rate for radiologists was only 70% of the level in 1991 (10,11).
At that time, there was much concern over potential changes in health care reimbursement, and many program directors were pessimistic about the future of graduating residents. From 1995 to 1998, as the job market improved for applicants (1214), program directors were more optimistic regarding the prospects of their residents finding jobs, and by 1999 virtually all who wanted to work had a job.

Maybe this is different. Maybe the economy and health care system will implode any minute. But if that happens, then all of us are pretty much f***ed
