"to expensive" is a subjective measurement.

If you are some podunk world in the boonies, low pop, ag,

non-industrial, etc then maybe so.

If you are a high-pop industrial world with a billion people and a
booming economy, a trillion credit defense sensor network is a credit
a head for ten years.

I wasn't the one to identify the affordability issue.

I think that the conclusion was arrived at by a compbination of statistical analysis based on some available world data from CT canon and the MegaTrav rules on world generation, etc.

What you say is only relatively true IMHO because world Economy is scalable, and income does not assume profitability.

In fact a lack of world profitability may be the cause of a desire to change leadership :-)

I hadn't looked in T5 (original edition) yet, but based on the real world, how many countries can afford to install a 100% air and sea sensor surveillance?
