They are scum. They bought something, promised to pay and skipped out because they wanted something else. Sorry, that is scum behavior and decent people won't have anything to do with them. Like the Mortgage Bankers Assocation, who bought a nice shiny new headquarters building in DC, then walked away when they decided they couldn't afford it, strategically defaulting to the tune of about $40 million.
ANYBODY who walks away from an obligation is beneath contempt. If you sign for it, you pay for it. I can understand if someone loses a job, suffers a catistrophic illness, but to walk away because you are underwater and want to get something better.....sorry.
Oh yeah, and just because some business does it does not make it right.
