I think the effects should stay, but be more gradual.
For example, instead of production stopping completely ... productivity should be linked to citizen-attitude.
Corruption should also be tweaked and linked to wealth. Strong local economy/low unemployment = low corruption, and visa-versa. This means building roads and linking it to your capitol/ports would decrease corruption, but leaving it in the middle of nowhere would be bad.
