An argument for ending the War on Drugs is that it would undermine the drug gangs. At the moment we have a baptists and bootleggers situation, where the drug ban benefits illegal providers, because it raises the price of drugs a lot. If drugs were legal, supply would increase a lot, lowering prices. Criminal gangs don’t actually have a comparative advantage at running efficient supply chains – if they did they would be running WalMart instead – so they will be out-competed by new, legal entrants to the market. This would dramatically reduce their revenues, making joining them less attractive, and leave them with less money to spend on sinful things.
And all of this is probably true. But…
Here’s another way of looking at it. At the moment some argue the US has a zero-marginal-product-worker problem; there are people who aren’t worth hiring at any price, because you can’t trust them not to steal from you, or break things, or insult customers, or get you into legal trouble. But, like the army before them, criminal gangs can make use of such people – perhaps because criminal gangs can make use of extra-legal motivational techniques. Normally, this would be bad, if criminal gangs were hiring such people to do immoral things like theft. But at present many of them are usefully employed in the socially productive activity of consumer product distribution.
And another group of thugs, who lack skills beyond the ability to yell loudly and order people around, get make-work as DEA agents.
So actually the War on Drugs is job security for semi-criminal ZMP workers, providing them with employment and protecting them from competition. Maybe pretty rubbish protection – it leaves many of them dead or imprisoned – but other forms of ‘protection’ for low-skilled workers also have some pretty negative consequences.
