Buying a few credits here and there for invites is not the same as running a service like munkbot (the time spent alone working on it greatly outweighs the time spent on the game by those monarchs, and that's not even counting the costs of hosting..etc).
Also, if I remember correctly the devs help out with free credits/mergers right?

You'll go a lot further with kindness/being respectful than with rage/qq/whining.. and that's not just for utopia but for life as well.

And for your fifa comment.. lol. So do you want the devs to charge everyone 60$/age to play?
