Why Change from Republic to Monarchy?

[al Roumi]

But a republic has happiness penalties for industrial advances, like absolute monarchy. Constitutional monarchy does not. Hence, as a C.M., I can upgrade all of my mines, farms, ports and industrial buildings with almost no garrison units required in my region capitols.

I have to say (as you can see from my post at the top) that I had understood otherwise; that there was a declining scale of discontent, going from worst to best: Abs. M, C.M., Republic.

Where have you seen that a C.M. gets zero industrial discontent?

And how does that work? I assume schools/universities still cause unrest? So are they the only sources of discontent in a C.M?

If so, I'm appalled and will have to add that to my list of grievances... as you said:

It is yet another one of those game design choices that irritates me, but we won't go there in this thread.

Once we have confirmed what the hell is going on, it would be nice to pull all the data on Govts together...
