make jail fun in some way
Horribly if taken out of context.
Anyway, I get that you removed labor jobs as they were horribly grindy.
But instead of completely removing, you could improve them.
Make them flow into the dynamic of the game.
They were almost the only job where you actually had to work.
For example, instead of an admin-build mine and forest, how about letting CEOs or the likes be able to buy the materials to build their own mine or forest.
Then they could start a real company with other players as their employees.
If the pay was great too, then enough will gladly be laborers.
And increase the diversity of those jobs too.
We could have: office workers mining papers, cleaners having to mop up small dirt patches, garbage men driving around town emptying trashcans, ...
An other idea is to let some building aspects only usable by certain jobs.
Only someone working in a garage can place a vehicle spawn for example.
Or only an electrician will be able to place most events.
Painting and building should still be done by the player though, or building would suck.
