Not to nitpick but not ALL prisons in the US are for-profit. They should be illegal though.
Fun fact - other countries that have for-profit prisons include the United Kingdom, Australia, New Zealand, Brazil, Chile, Jamaica, Japan, Mexico, Peru, South Africa, South Korea and Thailand.
This won’t do much since most of these prisons operate under state jurisdiction, but in 2021, President Joe Biden issued an executive order to stop the United States Department of Justice from renewing further contracts with private prisons.
