In theory, communism works

Those who love the free market and are committed to the ideology of small government, lower taxes and greater personal income freedom will often point to the great works that philanthropists have done over the years.

So the basic equation is this: Government spending on social needs = bad and inefficient; Charitiable giving to the needy = good and efficient.

But it seems that even rich philanthropists like Bill Gates can get it dangerously wrong.
