Yeah, real cute. Except for the guy who has to clean up the mess they leave behind! :) At home, it's usually Dad (yours truly). With Exxon's messes, all of us pay the price.
...And a perfect example of why legislation is necessary. I always tell people that companies will always selfishly do what is right for them; within the regulations. Having no regulation is a free-for-all, 'tragedy-of-the-commons', scenario where everybody fights for themselves; creating collateral damage -- usually to the environment -- wherever they go.
Civilisation is like a football game. Society marks out the pitch, lays down the rules and referees the game. The participants then do what the can within the rules. Without a clearly defined pitch, the rules and the policing, everything falls apart and everybody suffers. In the long run, even the players!
This is why liberalised markets cannot work.
As a former soccer (football) coach, I can report first hand on what happens when you let a bunch of kids loose with a ball and not rule or refs. Chaos, total dominance by the strongest players, frustration and anger, endless arguments, and, often, an injury. Not much fun for anybody, except maybe 1-2 bullies. Same with unregulated business.
