Ought Implies Can, Ethical Pronouncements without Economics Lead to Diastrous Public Policies

"One of the most common objections to free markets is that they ignore ethical considerations. In particular, critics argue that there are many things we “ought” to do that they believe will make people’s lives better off. We ought to “redistribute” income to the poor, they say.

Can the desired end (improving the welfare of the poor, for example) be achieved by the chosen means (income “redistribution”)?
