Lee Hazlewood, "Pray Them Bars Away" from Cowboy in Sweden

I'm told I should be thankful
For everything I got
So thank you for rock walls
And the brave bulls, thanks a lot
And thank you for the good job
At twenty cents a day
And thank you for the break time
To pray them bars away

It was during the decade of the 1980s that corporate ties to the punishment system became more extensive and entrenched than ever before. But throughout the history of the U.S. prison system, prisoners have always constituted a potential source of profit. For example, they have served as valuable subjects in medical research...

During the post-World War II period, for example, medical experimentation on captive populations helped to hasten the development of the pharmaceutical industry...

By the time the experimentation program was shut down in 1974 and new federal regulations prohibited the use of prisoners as subjects for academic and corporate research, numerous cosmetics and skin creams had already been tested. Some of them had caused great harm to these subjects and could not be marketed in their original form. Johnson and Johnson, Ortho Pharmaceutical, and Dow Chemical are only a few of the corporations that reaped great material benefits from these experiments.

[C]onvicts punished by imprisonment in emergent penitentiary systems were primarily male. This reflected the deeply gender-biased structure of legal, political, and economic rights. Since women were largely denied public status as rights-bearing individuals, they could not be easily punished by the deprivation of such rights through imprisonment.

[T]he prison sentence, which is always computed in terms of time, is related to abstract quantification, evoking the rise of science and what is often referred to as the Age of Reason. We should keep in mind that this was precisely the historical period when the value of labor began to be calculated in terms of time and therefore compensated in another quantifiable way, by money. The computability of state punishment in terms of time--days, months, years--resonates with the role of labor-time as the basis for computing the value of capitalist commodities. Marxist theorists of punishment have noted that precisely the historical period during which the commodity form arose is the era during which penitentiary sentences emerged as the primary form of punishment.
