The emotional valence of a policy does actually matter, since you have to sell it to voters (or whoever is in charge in a society). Technocratic governance is not a stable way to run society, as the last 30 years have shown. Any political agenda with a hope of being enacted needs to stir the heart in order to have any hope competing against others. The fact that a policy is provably a good idea and would make everyone better off in a theoretical world where everyone went along with it, is not even necessary let alone sufficient for it to become a real policy.
