The problem in Keynes thinking on "social services" is that it's impossible to gather all of the knowledge necessary to ascertain what those would be. That knowledge is dispersed among ~320m citizens (in the U.S.) who each have particular wants and needs. And even if you could somehow attain that knowledge in one place, the likelihood of finding consensus on how a particular "social service" should be offered is next to zero. The end result? Nearly everyone disagrees with some of what government implements, which breeds resentment and causes gridlock much like we're seeing today in the U.S.
It doesn't have to be that way. By decentralizing decision making down to a level closer to the individual (if not the individual), more people get what they want. For example, right now there's a federal mandate for health insurance. Not everyone agrees with this mandate, so why not at least push it down a level to the states? California can still have a mandate for health insurance, and Alabama can decide not to. And then, why not push it to the city/county level? If you don't agree with San Francisco's mandate for health insurance, simply move to Oakland. You don't even have to move states, let alone countries.
Why do so many oppose such a solution where everyone can much more easily find a place where they agree with the "social services" offered (or not)?
