Corruption

I just had an idea long ago that corruption should be based on the speed of communication between the main government and the city. Ways to speed up communication would include (sort of in order):
1. harbour
2. road
3. railway
4. highway
5. airport
6. phone
7. internet

This theroy would make countries less corrupt as the technology evolves (as in real life). In ancient times, a country the size of the US would be super corrupt, but now it has little corruption (any corruption that occurs has no realationship with the distance from the capitol)

Just an idea, please comment if I have forgotten something, had a sudden lack of logic, a question or anthing else you can think of.

Internet might increase corruption. Can you say identity theft?

I had suggested something very like this in a different thread. One of the suggestions, was that the chance of rebellion would be linked to the amount of time it took military units to get from the capital to the rebelling city (by whatever means). Your corruption model, could follow some of the same basic rules.

The United States incorporated the state of California early in its history, but I would venture to bet that the collection of taxes was not too good for the Feds! Communications does not do it alone (otherwise telegraph eliminates the communication/distance gap).

Well this theory will propebly be part of a larger theory for corruption.

But the question is, do you think this part of the overall corruption theory is correct? Do you have any ideas to improve this theory?
