El Salvador's prison system may be the world's smartest design

I know by now we all heard how El Salvador got a new president that some call far right and extreme, but facts are he has taken the most crime ridden nation in the Americas and turned it around. Mainly by putting ALL the gang members in CECOT a new supermax prison where they are never allowed to see daylight and are kept in clean but rough conditions.

It's not what they are doing to the worst that is so great. It's what they are doing for all the other prisoners. Prisons are education camps with "zero leisure". You sleep, eat and go to school or work and that's it. For every day you work you get two days taken off your sentence. What they are learning is almost every trade, CPR and medical skills and they even have culinary schools and a full university. The prisoners are well behaved and seem positive, because the alternative is being sent to a place worse than hell. But they have no drug issues, very little inamate on inmate crime and they credit it all to segregating gangsters and rehabilitating everyone else.

With the work force they have now they have been able to greatly contribute the the economy and build a skilled workforce of thousands quickly.
They have a textile factory that has 3 shifts of 2800 workers putting out constant stuff.

We could easily follow suit in my opinion.

Here is a well done Youtube video that interviews guards, prisoners and inmates. It looks more like a factory and a university than a prison.
