The United States has what is often said to be the world's highest rate of incarceration. I can't say that's literally true, but it's certainly one of the highest, and most of the so-called crimes on which that vast accumulation of imprisonment is based are nonviolent acts. Now presidents have arrogated the power to execute American citizens on foreign soil with no warrant, no criminal charges, no trial, no verdict, but only because one decides it's what he wants to do and his attorney general rubber rubberstamps it, the right to life is eroding. I wouldn't say it's yet disappeared, but it's fading away.
With the Federal Code over 200,000 pages long, and the Federal Register of regulations exceeding that with hundreds added every day, Americans are hemmed in everywhere they turn by that leviathan body of faux law, its vast and rapidly growing enforcement apparatus, and its exploding surveillance systems. We now live in a police state. There is no longer any way to keep up the pretense Americans still possess liberty.
Without freedom, it is not possible to pursue happiness. That has fallen away along with the other basic rights.
The answer, then, is clearly negative. Americans have the rights of life, liberty and pursuit of happiness, just as do all people everywhere, but they have lost the power to exercise them, and the source of that deprivation is the government they still like fondly to imagine is theirs.
