I don't think anyone considers our system of governance to be particularly efficient, and we all understand that it is not perfect. But then many of us recognize that the alternative of a decentralized system without extensive regulation is also problematic, as it entails all kinds of market inefficiencies and failures that no one wants. We should all recognize that a centralized government does some things extremely well - e.g. how often do we think about the fact that the elderly used to be the most vulnerable segment of the population with the highest rates of extremely poverty, and now the elderly are probably the most secure segment of the population with the lowest rates? That's government policy at work. And we should all understand that the current system is wildly inefficient in many ways, and is often distorted by our unique system of interest-group politics and our imperfect system of federalism.
That said, even if no one loves our system I think most agree that it's dramatically better than virtually any other system that's ever been invented in human history.
With that as a backdrop, instead of just railing against what's in place let's think for a minute about some alternatives to our system of governance.
For progressives, social democracies like those in Scandinavia are often seen as closer to the ideal form of government. They have less extreme poverty, better health, better education systems, more mobility than the US. As a tradeoff, they are not particularly efficient in many cases, they have heavy tax burdens and more of a communitarian style of life. For those who believe that government should be primarily focused on promoting society-wide goals like reducing extreme poverty, opening up opportunity, enhancing education and improving health, these countries are a model b/c they do a better job than the US of achieving all of these goals. But they are not ideal and have tremendous faults and problems, which is why many progressives might not actually choose to push our country in that direction.
What are the best models for conservatives or libertarians that actually exist in the world? What are the advantages of moving toward these models and what are the disadvantages?
