The Prison Industry Corporate Database.

Never forget that slavery in the United States was officially abolished in 1865, except in one key area -

 

Thirteenth Amendment

Section 1

Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.

Section 2

Congress shall have power to enforce this article by appropriate legislation.

 

Can one guess why?

Answer - it's a function of capitalism  - the need to exploit a cheap labor source for profit.

Think that's hyperbole? See if your employer shows up here.

Sadly mine does. So does several ex-employers.

Honestly I think it'd be easier to create a database of corporations who don't use prison labor.
