While you could argue that being born and raised in extreme wealth makes you apathetic to the trials and troubles of the poor or those financially below you, which anecdotally, I think most people have witnessed in some fashion, this "affluenza" is complete shit, he might not care if he killed people, but there's no way he didn't know what he was doing was wrong, he was driving drunk on a restricted license that was restricted for previous drinking and driving.
I honestly think everyone in that courthouse knew it was a ridiculous defense. I don't think even Couch and his parents bought into it.
He had/has a crafty lawyer who secured a psychologist to testify (ie paid him well) and invent "affluenza". The Judge for some reason accepted it, which is odd as it was brought up that years and years before, she had sentenced a [financially poor] teen who killed one person while driving drunk to 20 years in prison.
Boyd sentenced Miller, a troubled teen whose mother was a drug addict and who was being raised by his grandfather, to 20 years behind bars."The court is aware you had a sad childhood, but you are fortunate to have a grandfather who is so committed and loves you," Boyd told Miller during the sentencing. "… I hope you will take advantage of the services [offered by the Texas Youth Commission] and turn your life around."

It will probably upset some here to know that he's being held in a high security part of the prison for fear of his safety, where despite having other inmates in cells around him, he has no contact with them and has apparently been eating lots of Bluebell ice-cream which he's allowed to buy from the commissary.
TL;DR, he's not getting anally raped
