Although, I find the idea interesting that we could solve a supply issue in a field by training our prison population. Too bad the American Medical Association would never allow competition :P
The inmate is also getting dignity and practice at regular life, which might convert a % of them to non-criminal life (I forgot the word for it).
Still doesn't mean taking 80% of the wages of prison laborers is anything but exploitative.
EDIT: Allowing prisons to profit from the labor of prisoners creates a perverse incentive for the companies running prisons to keep prisons full. Maybe it works in places where prisons aren't run for profit.

There's a film on it https://en.m.wikipedia.org/wiki/13th_(film)
The fact that imprisoning people costs a lot of money is one of the few things keeping the U.S. prison population in check. That's not a problem that needs solving.
In Germany prisons are to large parts "self sustaining" thus inmates do the cooking, washing, carpenter work, metalworks, car mechanics works, ... including proper apprenticeships in different fields compliant with Germany's apprenticeship system.
Some prisoners also work on service for external customers, one can even buy products directly from jail: https://jva-shop.de/
However pay is very low, way below minimum wage and different cost the state charges prisoners is directly deduced and while in jail the only place they can spend the money on is the shop inside, for cigarettes, sweets, TV sets (requires special permission), ... while that shop owner charges prices based on his monoply ...
But the general idea of German jail system is that after jail inmates should have a chance to find a job with some education etc.
Often failing for different reasons, though.
I understand if you have offline computers. I understand if the computer needs to be behind a plexiglass wall and the mouse and keyboard need to be chained down. But quickly these will pay for themselves. Data Entry pays significantly more, I imagine there are plenty of white collar criminals with tech skills that could make $30-$100/hr.
Even if you only let the inmate keep 20%, the inmate is getting skills, money, the system is getting extra money, the company getting the data entry is getting cheap labor.
I can't see too many downsides other than the initial set up cost. Pretty sure the right side of the aisle will see the $$$ and approve. The left side should also see the $, but also know how humane and potentially rehabilitating.
