I guess you like what you see today with your wars, torture, indefinite detention, and execution without a jury. A government powerful enough to grant you a thing is powerfull enough to take it away. As history has already revealed, will take it away, no matter how good the intention was going in. That is because 'power corrupts,' and the same human error that infeebles your free market of child labor, also infeebles every institution, especially government (where there exists child pornography rings, for example.) People don't magically become enlightened just because they are in the public sector, you know. It seems obvious that you wouldnt trust a ceo to be answerable morally to their board members, would you? So why, then, would you think a councilmember would be socially just?why do you people put government employees on a pedestal? Do you imagine changing their title will make them answerable to the people? The fact remains that the best government is the smallest government, and there is no smaller government than self-government. That is to say, there is no better decision-maker for humanity than you for yourself.
Like Ghandi said, become the change you want to see. If it is safety net you want, then become the safety net. If you figuratively teach yourself to fish, then you become your own safety net. and your children might even be blessed knowing they won't have to demand safety nets from others, either, since the can create their own out of thin air just like pops.
