Except during the data science craze of 2015s, there was never a situation that you could just have a phd in any field and get any "phd level job", so whatever pedantic idea you have of what phds learn, not a single person who's hiring phds agrees with you. On the contrary, even most phd professors treat you as only a vessel of the very specific topic you studied during your phd. Go try to get a postdoc in a top lab when your PhD was not exactly what they work on already. I know I tried! Then gave up.
