This would be applicable to any country though I live in the USA and will use the U.K. as an example…

There is a definite economies-to-scale going on with the globalization of anything… actually, with anything, never mind globalization… Example: the U.K. has surveillance in London everywhere because of rampant crime and the ease with which most crimes could be commited and go unresolved… was the total cost for such a surveillance system worth the investment? Are the returnes they are getting outside of financial – citizens feeling better about safety, for example – also making this investment worthwhile?

India, China – would the do the same with the large cities subsidizing the smaller cities

Now – zip over to a small town that is experiencing high crime as well… Should they invest in the same surveillance as London? That depends — ae all the residents capable supporting such a system (the median income and tax base) or should cities like London subsidize such a system from the savings London has realized? With this questions we enter the preference of national government involvement…

Not an easy answer…

The better approach: possiblity the education of the citizens to the ways and means of the manipulator focused on the level of the citizen…. from the diplomat to the trade merchant to the border agents to the average citizen…
