Remember when VW did all that computer magic with emissions controls.
Only a mid level engineering manager went to jail.
The diesel emissions will probably cause cancer in people in the streets. CEO's need to start going to the gaol long term , and we need to start banning those involved from being able to run, own, or hold shares in corporations outside of blind trusts ever again.
The car industry support hundreds of thousands of jobs all over the world and in the respective countries of each manufacturer. There would never be any strong action taken against them, this would be hurting the government who took it and its people.
On a side note. Big internet companies will never enjoy the same level of political support. They don't support any job and don't pay any tax where they get their money from. It's a bunch of nerds in the west coast and that's barely caricaturing. If anything, the bigger fines will come from Europe rather than Washington, because politics.
60 million advertisers use Facebook to run ads...I am pretty confident that they have a strong economic interest in the government being nice to Facebook.
