Yes. The overall numbers at present are broadly similar (2.2 million prisoners in the US at present, compared to 2.6 million at the peak of GULAG, though that was drawn from a smaller population), but US prisons have much lower death rates (especially compared to WWII-era GULAG — hopefully there will be no similar invasion of the US and so we will not have the opportunity to see if a wartime US massacres its prisoners in a similar fashion), and a smaller fraction of the prisoners are slave laborers (in GULAG it was nearly 100%).

Presumably if the US is beginning to institute Soviet-style censorship, it indicates a strong risk that prisoner numbers will go up and the treatment will get worse.
