Answer:
In parts of the United States there are prisons which, instead of being run directly by the government, in the traditional style, are run with private interests. The state authorities allocate money to the financing and make sure that they follow the same standards as state prisons, for example in terms of cells, food, work, rights and other conditions.
Advantages and disadvantages arise from this situation. As for the advantages, we can see that the government invests less money than it would invest if the prison were state-owned, so less money is invested in an activity that is not productive in itself, being able to allocate that public money to another type of expenses most necessary to improve the life of society. In addition, the fact that private prisons coexist with state prisons implies that the prison system is not saturated, since many investors can create new prisons, avoiding overcrowding of convicts as happens in other parts of the world.
As for the disadvantages, the main one is that the prison ceases to be a punishment for the inmate and a protection for society to be a business, so that since there is an economic interest, there can be an over-incarceration of the accused in the various criminal trials of the country. In addition, the lowering of costs in the prison day to day may lead to the violation of the rights of prisoners.
