There's a mechanistic reason why it's a bad choice. Government is by necessity a hierarchical system, by its very nature its process of allocating resources requires a concentration of wealth and power. From first principles, there's no way around it. Any system that enforces 'good feels' top-down is unstable and has a half-life; systems of social support will eventually be redirected to benefit the wealthy. For example, if we go to single payer healthcare, it eventually will become a vector for lining the pockets of phamaceutical companies.
