Paulo,
In Delaware, we have zero sales tax, low income taxes, and low property taxes. This is made possible by the number of corporations registered in Delaware. The tax breaks they receive are considerable, but the overall numbers of "Delaware Corporations" are HUGE, thus we normally have a large surplus in our state budget. However, due to our state government overcooking the golden egg, this goose's eggs have turned to lead. Delaware has been suffering a budget deficit for the first time in many, many decades.
It's not just large corporations like Ford, Pepsi Cola, and the like that are registered in Delaware. Small corporations by the hundreds of thousands are registered here as well. And on an international scale, many large tankers, container ships, etc., sailing worldwide, are registered here. 99.9% of them have never been in Delaware waters, yet they have a Delaware hailing port. As a tax haven, Delaware still ranks right at the top.
BUT, as a result of these wonderful benefits..... corporate tax breaks, no sales tax, and low income/property taxes, Delaware has become the retirement "Mecca" of the mid-Atlantic coast, and THE place for young and middle aged folks to buy a summer home at the beach. Lucky, lucky us!

Now, Delaware has all of the great things everyone else has enjoyed for so many years.....overdevelopment, increased crime, ridiculous traffic gridlock, increased pollution, complete overloading of our infrastructure, economic woes, etc.
Sadly, it's not the Garden of Eden anymore, more like a festering boil, just waiting to burst.
