Dad asked me one time while was in the hospital for a week “did you notice there is only one white person working here? They are all foreigners”.
Yes Dad...they are the only ones who can get approved for a grant to go school.
I haven't been in hospitals for more than a decade, but recently have spent a few days at two (relatives, friends) and it was instantly noticeable among nursing staff, and somewhat less among the medical cohort...
