Not as greedy as the Southern states were. But that's another subject.
Is it not enough that Southerners wanted to disassociate from your ilk, without having to abandon their homeland as well? Is that really what got Lincoln's panties in a wad? that Southerners thought more of living in their own country with blacks, Mexicans and native Americans absent yankees?
Oh you could have taken your real estate with you. Although how happy you would have been with the blacks once you couldn't own them any more, or with the Indians when you couldn't expel them any more, or with the Mexicans once the confederacy tried invading them, are all open to speculation.
Tell me sport, just how does one take an entire state, of even a few acres of land physically with one?
