Post modernism embraces this though, and it is rampant in the West post Kant/Nietzsche. When you create your own truth and morals, you are going to disagree with people about stuff like this :)
I'd hardly call this embracing this thought. The hundred dollars you get is nothing when you destroy the environment.
Yes, this behaviour is rampant throughout Western society, it's pretty much embraced by capitalism. It's still "who cares about $x, as long as I can get my $y". It doesn't really change the argument much if $x is open source and $y is a free t-shirt, or $x is the habitat of these creatures and $y is gallons of oil.
Don't really see how postmodernism fits in with this though.
