If they stop all of the oil immediately, they've already done damage that we'll be cleaning up for decades. They've probably destroyed about 100 billion worth of revenue in the fishing business alone over the next 10 years.
And will they be held liable? For causing 100s of billions of economic damage over the medium-long term, let alone the environmental damage? Of course not, because they have good lobbyists and 65% of congress is either corrupt or an idiot who thinks "drill baby drill" is all you need to know about energy policy.
Yeah, that's admirable. It used to be we cared about justice in this country, and now we just admire those who evade it the best while they're screwing us.
