“Most of economics can be summarized in four words: ‘People respond to incentives,’” says economist Steven E. Landsburg. “The rest is commentary.” The same can (mostly) be said about electoral politics: Politicians respond to incentives.
Politicians are often derided for following the crowd rather than leading on public policy. But in doing so they are often acting rationally. To gain votes you have to give people what they want, even if want they want is ultimately harmful.
When we can see or predict the destructive outcome of such policies there is a tendency to assume the politicians motives were dishonorable. But more often than not, politicians who endorse bad policies have noble motives — even if it is nothing more than the desire to give voters what they asked for.
I believe that is true in the case of Hillary Clinton, who became the first major presidential candidate to ever recommend paying all disabled workers the minimum wage. I assume her motives are perfectly pure, even though the result would lead to increased unemployment for disabled workers.
