Another Sowell gem

If you could knock a little something into the heads of young liberals, what would it be?

I'd like to get them to think in terms of incentives and empirical evidence, and not in terms of goals and hopes. Over the years, I've reached the point where I can hardly bear to read the preamble of proposed legislation. I don't care what you think this thing is going to do. What I care about is: What are you rewarding, and what are you punishing? Because you're going to get more of what you're rewarding and less of what you're punishing. -- Thomas Sowell
