I tried to move things from specific to general to help explain the problem
If you persist in calling VW "unfettered entirely amoral capitalism", why don't you tell us what kind of company and management you think would be better.
It can't be fully state owned facilities, because they had an even worse environmental record when they were tried in Europe.
The entire market is amoral-capitalist. If you can't keep up with the cheating, shareholders screw you over. That's not to excuse anything VW did. However, just because a single player is "partially owned by a government" doesn't make it any more likely to be moral; What it would take is for all the companies to be more strongly vetted/regulated.
