Ironic that you chose socialized medicine as your example. The primary arguments in favor sound essentially the same as those made by Marx and Engels.
Frustration with our current healthcare system is largely justified. If only we used the foundational principle of modern economics - price - it could be so drastically improved.
Sadly, the downfall of our system began when the Roosevelt administration thought an employer sponsored system would be a great first step toward socialized medicine. While it kept the initial means of production private it also eliminated ‘price’ - next to property rights the two most most important concepts that have lifted billions out of poverty - out of the equation.
Real healthcare reform leverages the miracle of ‘price’ rather than repackaged Marxism.
