Will there be simple jobs on Mars base? Someone to sweep the floor, someone to bake a cake, etc? Will they produce enough value to justify enormous resources to keep them alive in such hostile environment?

And even people with important jobs, they would work maybe 50-60 hours a week, but consume resources 24/7.

On average, the value all humans produce in a week might not be enough to keep them all alive for a week.
