I have no problem with that sleepy old idea, except to say that it is wasted on the pale end of the spectrum. There is a possibility that a modified concept would have a grander fiscal effect, all the while providing us with unceasing social-media entertainment. I speak of drug-testing those who feed at the higher end of the public money trough, beginning with the President and then on down through the vast herd of federal, state, and local politicians. Some taxpayers may prefer once-a-week random urine samples of the high-and-mighty, verified by publicly available video, but since we are all used to politicians pissing on us, most would find a poetic attraction to witnessing blood being drawn from the parasites.
Count on my support if the idea is reconciled to include what I have outlined above. If for nothing more, do it for all the underemployed phlebotomists and their children.
