Corporations don't have morals. Aspiring businessmen don't take ethics classes. There are only two questions: Does it increase profits? Is it illegal? They will ignore rule two if none of the board goes to jail and the fines are less than the profits. They would sell you leaded gas today if they earned a fraction of a penny more per gallon. They do not care about anything aside from profits. That's capitalism.
This is why libertarians are even stupider versions of Republicans. At least Republicans are just corrupt assholes. Libertarians are corrupt and stupidly naive assholes.
Its a perfect example of why we need mandatory jail sentences for these things and fines that always oncorporate double the profits of an illegal action.
The global authorities would need to keep the US out of the equation as they would probably say something along the lines of 'give us a percentage and we'll look the other way... Again.
The US is very deep in corruption and populism. I pity the citizens of that country. Education is being dismantled, people are being brainwashed every day. Its disgusting, really.
