The drug war:
One million prisoners doing hard time at any given time.
More millions have done hard time at one time.
Perhaps ten million with life ruining, unnecessary felony convictions -- even if they did not go to jail.
One hundred million addicts saved? Maybe not one.
A "very enlightened" policy whereby we threaten to ruin your life: we will break up your family, we will take waste your years, we will make you unemployable thereafter -- if you take the chance of ruining your life using a dangerous drug.
Meantime back at the economy: we have had a 1939 level federal minimum wage level ($4.50/hr, w/no taxes in FDR's era -- adjusted for inflation) to combine with the prohibition. What do we naturally get?: street gangs selling prohibited substances. Only difference between the today and the '30s: the gangs are African-American and Latino instead of Irish, Italian and Jewish.
What a wonderful set of ass-backwards policies.
