Ask him if Communism works. If he says yes - give up - he is a lost cause. If he says no, then point out that, like Communism, Keynesian economics always works in theory but never in practice, because it ignores one huge fact, inefficiencies generated by governmental bureaucracies and politics. The free market has an anti inefficiency mechanism by punishing the wasteful and inefficient, while politicians are regularly rewarded for the same conduct.
Taking money out of the free market and having the government spend it does nothing more than introduce a whole new layer of inefficiencies.
