The unacknowledged myth of public policy is that there is no such thing as "the public good". No treatment -- drug, government policy, 'planning' -- can benefit all people. E.g. People in your country are suffering from malnutrition so you decide to subsidize certain crops. Congratulations now high fructose corn syrup has created an obesity epidemic. In the medical field this is acknowledged under the study of 'iatrogenics', that harm which results from attempting to help.

Unstudied, or unstudiable, government policy results in whole societies being forced to take metaphorical drugs in which politicians, without any supporting evidence, tell the populace that this policy will help them. And yet people who live in the real world see the exact opposite. The economic and social isolation of the political class exacerbates this effect.
