Free Market Lemonade

Dani Rodrik:

Markets are the essence of a market economy in the same sense that lemons are the essence of lemonade. Pure lemon juice is barely drinkable. To make good lemonade, you need to mix it with water and sugar. Of course, if you put too much water in the mix, you ruin the lemonade, just as too much government meddling can make markets dysfunctional. The trick is not to discard the water and the sugar, but to get the proportions right.
