Nevada is planning on establishing business areas that allow businesses to set up government functions separate from local governments. These "innovation zones" are an interesting experiment into anarcho capitalism, like in cyberpunk 2077. Business entities would be allowed to impose taxes, form school districts and courts and provide government services.
Under current American constitution, there is a legal loophole for slavery. 13th amendment: "Neither slavery nor involuntary servitude,
except as a punishment for crime where of the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction."
Currently this is exploited by private prison labour corporations like CoreCivic, it's publically traded & dividend paying (good for your retirement fund). They are incentivized to increase the prison population, could be related to why America has the largest incarcerated population in the world at 2 million people. Prison labour is used to generate profit and funding is provided by the government as well. Euphemism for the American Gulag (although they would demonize other nations for having a similar system).
Would be interesting to see how private enterprise would exploit legalized slavery in a system where they run the government/courts as well. It is my assumption that incentives are towards profit and productivity, resulting in higher efficiency and heavy neglect towards less productive areas that we normally take for granted. Much like the market based American health care system, we see extreme exploitation of the average user but provides great funding to develop high end medicine, I expect similar to be the case with this experiment.
Lens of traditional morality might be insufficient in tackling the challenges of the future. Better have an isolated experiment, monitor its progress and learn lessons from it than commit to a radical concept for the entire society similar to Shenzhen and other SEZs. For better or for worse, if implemented this will be an social-economic experiment worth looking into.
