Not so much any longer. The US incarceration rate is at a 20 year low and keeps falling. We've been reducing the prison population for a decade now.
For example the black male imprisonment rate began declining finally during the second year of George W Bush's Presidency. It has dropped by around 36% since the year 2001.
The US incarceration rate began declining about the same time we began building more private prisons (for the record, I'm ideologically against private prisons), which entirely goes against the common propaganda that private prisons would result in a lot more people in prison. Turns out, of course, that it was evil government actions and policies that did all those very bad things, like the war on drugs and putting millions of people in prison unjustly and holding them there for excessive durations of time (mandatory minimum sentencing laws).
