I don't think it's out yet, though I may be wrong about the people overseas. Some of those scans above are from the book so it may be available in some places. It isn't destroying the world as much as it is wrecking nearly half of the US. If you freeze-frame the part in the trailers where Lex is about to say "WRONG!", you'll see a huge map next to him of the US, but all of the east coast is pretty much broken apart (it's either that, or it's New Krypton, can't really tell). So he's just causing enough destruction to the point where economy wouldn't be pointless, but going to Lex is your only way of living.
