Do the research yourself or pay me a consulting fee to do it for you. There is only so much research I'll do for free.
Yes, you can argue that dollars are not equal but bear in mind that New Jersey does have military facilities as well (Fort Monmouth, Earl, Picatinny, McGuire, as well as federal employees in various agencies). And a heck of a lot of welfare gets sent into the "red" states. I know this is counter-intuitive for many Freepers but it really isn't difficult to understand. It's all about income.
If you look at average Median incomes (for example, here), you'll see an average income in Kentucky of $39,300 but $63,800 in New Jersey. New Jersey has about 8.6 million people while Kentucky has only about 4 million. Now, consider that the tax brackets for Federal income tax are not indexed for the cost of living. That means that fewer of those 4 million Kentuckians are even paying taxes. They are paying less in taxes. And there are less of them paying it. This is so obvious for conservatives when it comes to explaining why the poor didn't get a tax cut.
Poor people pay less in taxes. The people in the rural South, rural Midwest, and rural West are poorer than the people on the coast and in the cities. There are fewer of them in the same physical area. It is more expensive to do things like build roads, sewers, or electrical and phone lines and it takes longer to visit each person because each person is father apart (this is where the rural "Baby Bell" USWest got screwwed). Put it all together. This isn't that difficult to see once you stop assuming that rural living is cheap. Ask USWest/Qwest how cheap it is running a rural utility compared to an urban utility.
