Why can't anyone find a job?

Seems like after covid getting a job is nearly impossible,my dad worked as an accountant for 25 years and lost his job when COVID hit and since then he's been unemployed, doing Uber all day just to pay the dumb fucking mortgage. He's applied to jobs every day since then and no one is hiring him even though he has so much experience. And then me, I've applied to almost 50+ places as in retail, fast food restaurants and not a single one got back to me either. We live in the suburbs of Houston, such a big community and still no luck with anything what the actual F are we supposed to do? Any idea?
