Are there "so many" though? There have always been more aspiring actors than working actors and more aspiring musicians than working musicians, influencing is just more of the same. And what teen/young adult wants to be told "hey, forget your dreams, you can be a cog!" My brother went to school to be an RN and he hated it; health companies have been bought up by venture capitalists who understaff their facilities and overwork those they have until they burn out and leave, all to maximize profits for themselves and shareholders. There are a lot of problems and shortages in key fields, yeah, it's absolutely an issue, but blaming it on kids with stars in their eyes who want to shoot their shot (and most likely end up in traditional employment down the line anyway!) instead of the economic and societal issues caused by greed is dishonest, ignorant, or both.
