Some of what I do is bullshit, but most of it isn't (almost all health and education related, mainly freelance, split between several companies/organisations). A lot of the information I provide is then used by professionals to help make decisions and/or advance their knowledge. And that was a deliberate choice about 25 years ago.
I could have made a lot more money by going into a more corporate/finance/commercial oriented environment but I couldn't have handled a lot of the people. (I still encounter them occasionally although I've lost touch with a lot of them over the years.)
I think for some people the sudden realisation of the sheer amount of bullshittery in their jobs is one of the many reasons this lockdown is proving very, very difficult on a personal, spiritual level. There's one particular previous employer that had utterly mastered the philosophy of management by pointless meeting and I really wonder how they're coping. (With endless Zoom streaming, probably.)
There'll be other sectors in time that will grow, I'd have thought farming (thank you sincerely to ALL farmers on here), food production, food security, AI, cybersecurity and surveillance, cybercurrencies; teaching and healthcare will continue, but morph dramatically (already seeing "telehealth" type projects), but it's going to be an, er, interesting middle bit! I'd hope the penny might also have dropped that machine translation isn't always enough when it comes to medicine and science, too. (Huge understatement there.) And I'd be surprised if there isn't more need for Mandarin and Russian speakers/readers in the very near future.
(The jury's still out in this house on MPs, members of the House of Lords, Royal Families, 'Slebs who don't actually entertain or play anything [we really hope most actors and singers and comedians, and some footballers come through this in some form], and PR, HR and marketing professionals.)
Plus I can do some useful-ish things outside the day job. Just don't ask me to do things that involve brute strength or dexterity. ;)
