I'd say that "pushing a broom" is a straw-man of a job that doesn't actually exist anymore, if it ever did.

There are many millions of busses to drive, bags to load, passengers to drive around, trash bins to empty, and floors to be swept, vacuumed, and mopped. I think perhaps you underestimate the massive size of the unskilled job market.

0 of those jobs consist of solely "pushing a broom," which as a phrase dehumanizes and strips "unskilled" workers of their dignity.

Busses are definitely a specific skill requiring specific certification. I don't know if dedicated bag loaders exist these days but everyone has other job requirements. While yes, the market for low skill jobs is large, I think you're still diminishing these roles.

I see a lot of this on HN and it’s disappointing. Place can be a bit too steeped in privilege and survivorship bias at times.

Bus drivers are not making MW anywhere.

And they require skills. Which puts them firmly out of the mindless, worthless, broom pushing category that was being constructed here.

Tell your CEO to do janitorial work for a day and ask them how qualified they felt to do unskilled work.
