Socialism can not be controlled. Once you accept the premise, it is just a matter of time until everything goes down the crapper.
Not to hijack the thread, but I believe while difficult to control, and largely unnecessary, there are areas where socialism is a necessary evil in small doses, with tight controls. The controls could involve a very rigid balanced budget process based upon a limited tax revenue structure and the prohibition of riders (a line item veto gives too much power to the executive branch).
Only "x" amount in the pot for the budget each year, and that being far less than we have now. Support for the mentally ill that have no surviving family when voluntary charity comes up short gets its share -- perhaps. Maintaining a credible defense gets its share. Highway and infrastructure support -- its share. The bridge to nowhere -- hard to sell that one so it doesn't happen. NEA? With a far more limited pot of revenue maybe it loses out to some child nutrition support program. But, maybe more of us have more discretionary income to support the arts with or greater take home pay. Etc.
The most important bureaucracy would become an aggressive and well funded GAO to police the other bureaucracies, many of which will be eliminated and those that remain reformed to become lean, non-political and focused on results with mandatory staffing and org chart limits. Few chiefs, more motivated Indians, smaller missions. Work on one of the models that reduces the formal power of special interests both Union and Corporate.
This would also drive more activity back to the states. State taxes would increase, but... States would then have to compete more with each other for businesses and tax-paying populations. Too onerous a tax environment and the middle and upper class and businesses move. Pays to balance, etc. Simplistic and off the cuff, with some likely issues to be addressed but somewhat along the lines of my core government philosophy.
This comes up short of what a Ron Paul would like to do, and is perhaps no more likely in the real world, but I would be happy with this compromise solution.
