Didn't he, though. He had a great supply, underground, from perfect socialist sources: Cummins, Angola and other squalid prison farms of the South.
This article, like so many, attempts to blame the problem on for-pay donations. Those were bad, but they were a trickle compared to the truckloads of blood plasma pumped out of filthy prisons. And for-pay blood draws were not free-market enterprises but were made possible by regulation (blood shield laws). That let the fly-by-night operators act irresponsibly while remaining immune to lawsuits or prosecution.
I remain convinced that "free" blood donations are a bigger swindle than anything the petty crooks did in slums and border towns, and that the free market, policed by competition and open market practices -- with no regulatory protection -- should be the safest source of blood.
