Is it true that there are 100 people in prison in the United States? If so, why?

In addition to the high crime rate, many prisons in the United States belong to privatized groups, and holding prisoners has become a business. When prisons are privatized, the government will provide subsidies. If the imprisonment rate is too low, the profit will be low. If there are more prisoners, the government will provide more subsidies and prison owners will get more profits. In recent years, it has been reported that in many states, local prisons collude with the courts, and judges impose heavy sentences in order to make the prisons profitable and the judges take kickbacks. Even funnier, in order to increase profits, the conditions of imprisonment are now broader. For example, under Trump's highest voice, the federal government and states took the opportunity to tighten immigration policies, expand the number of people sentenced to imprisonment for suspected illegal immigration, and increase the prison term to provide more prisoners with longer detention time. In 20 10, despite the opposition of the federal government and public protests, Arizona introduced a tough new illegal immigration bill promoted by CCA. The state believes that as long as the police suspect that someone is an illegal immigrant, they can imprison him without trial. It is illegal to hire illegal immigrants, even if they are transported by car. Anyway, I just want to send more people to prison. As an industry, prison can already do politics. Private prison companies gave Trump some "political contributions" at that time. Sure enough, Trump strongly supports the development of the private prison industry, and naturally more people are imprisoned.
