The justice system punishes people. There are around 2.2M people in US prisons.
Schmidt was involved in corruption --- for profit --- which duped ordinary people into releasing around 1MM tons of pollution in to the atmosphere in a single year; about the same as all the power generation for the 66 million people in the UK.
What's the scale of the damage that most of the other 2.2M people in prison did? Sold some drugs? Stole a crappy old car?
