I'd rather have a wonder that acts like a courthouse in evey city(I hate CTP, but I think it had one like that). BTW police stations only help war wearyness.
They wouldn't do a wonder that does a courthouse in every city since courthouses produce culture. BTW, I think you will all eventually get used to the culture if you adapt your strategies and play style a bit. Its certainly never been a problem for me, and I've had some huge empires (57 cities biggest so far).

How about the ablility to put a certain amount of gold per turn into the courthouse of a distant city. The more gold you put in, the more effective your courthouse will be.
Realworld equivilant - If there is a high crime rate in a city what does the mayor do? Hiring more policemen (which costs money) is a typical response.
