You're assuming that the point of the American justice system IS to refrain and rehabilitate. It's not.
A for-profit prison system seriously is low-key the most fucked up thing in a country full of fucked up things.
American prisons exist to make a profit for their investors. They do this by both government subsidies (which are calculated per inmate) and using the prisoners as cheap labor that they legally only have to pay pennies.
The system NEEDS a continuous influx of prisoners (slaves) to remain profitable. Rehabilitation is anathema to that.
For me it was hardware ethics.
Spending thousands every couple of years because a marketing department tells you your old device is suddenly shit just doesn't sit well with me.
I've used the same $400 dollar phone for three years now, keeping it updated with lineageOS. And I've kept my trusty 6 year old editing desktop relatively capable with routine part upgrades and Linux.
Our entire economic system is based on making people buy new shit as often as possible, and that's so ridiculously unsustainable it's insane most people just put up with it so long as they can keep their nose down watching tiktok.
