In Surviving Mars, I had a similar problem.
SM unlike the usual city builders, builds a command economy and starts with no colonists (just drones) and then they show up ten or twenty at a time. There are no higher salaries or higher standards of living; what they make for the community is there for everyone.
And then I directed them to build a university. Education was open to everyone. PHDs for everybody!
But then everyone wanted to be a scientist or engineer. It wasn't enough to be smart yet stuck with the job of grocery operator, or in freight inventory management. They wanted to use their newly developed skills, and explore strange new worlds and seek out new life and civilizations (even if in the lab rather than by starship)
Underemployment was a factor, and my custodial staff empowered with degrees in philosophy would lose morale and eventually go renegade (turn to crime) when I forced them to just continue to work the cranes and stock the grocery shelves.
Well, I needed an example.
