Regardless of that perspective, here's a truth: most inmates will be released at some point. As a matter of fact, alot of the inequality you reference is a result of those with criminal backgrounds and the socioeconomic conditions that got them those backgrounds. We have a rich set of statistics about what happens to people in that situation: desperation -> crime -> prison -> repeat. Personally I don't like that world. I want to feel safe in my world, and anything we can do to short-circuit that recidivism cycle makes us all safer.
The "but our jobs! but our pay!" refrain is a common one, but our industry has WAY too many job openings for this to be a legit worry (the very presence of the h1b visa proves this). As for salary, as those jobs get filled, whether by bootcamp grads, or journeymen, or trained individuals with a criminal record - it will push income down for some. Some incomes are a product of scarcity, and you only need to look at a supply/demand curve to know what will happen to prices. In the late 90s, you'd spend tens of thousands of dollars to get a basic website. Now you can get one for a few hundred.
