Way, way, waaayyyy off base there, bud...
Do you own a home? I'm guessing not, based on your position statement.
How you figure the society in general is 'bettered' by another strip mall or office building? Hospital or school, maybe....but more commercial properties?
Nope...that's just for tax revenue..not the greater good of all mankind.
Eminent Domain is meant to prevent one or two hard cases from blocking the overall improvement of a community, but you need to consider what is actually an overall improvement...strip malls aint it. For example, a small town needs a new regional medical center to improve healthcare and emergency services for folks who are maybe miles away from medical care, but Old Man Cooter refuses to sell his chicken farm cause he likes the view. This would be a case where the greater good is pretty apparent, and the resistance to sell is perhaps of questionable rationale.
The problem is (it seems to me) that municipalities have discovered a way to start using this principle to line the municipal coffers with tax money, while also granting political favors to big-money developers for future paybacks.
Lastly...nobody EVER gets more than they would on the open market. It's the government, for Cods sake...you get raped, and no two ways about it. And, as has been pointed out...you effectively have little to no appeal. Take it or leave it, and have a nice day.
It should take an extraordinary and hugely expensive process to force a family off their land for almost any reason. Lately, rather than getting harder to do, it's become ridiculously easy.
Just wait til they come for YOUR house, and I'll bet you feel differently.
On a different note in general...careful not to confuse sprawl with eminent domain actions. Sprawl is a direct result of increasing land values in growth zones...quickly enough, a famer's land becomes so valuable to developers, that he can no longer see the fiscal sense in working like a dog from dawn to dusk, when he can make more in one sale than he might in the remainder of his life farming his plot. As soon as that happens, we promptly bury productive, arable farmland under asphalt and concrete foundations.
I can't imagine a better use of rich, fertile land than another mall parking lot...
