I sincerely believe there are some things the government should run with our tax money because they are a collective duty to the collectivity. Among these are health care, education, transportation, basic utilities. These are things which cannot be left to the profit-motivated private sector alone; they leave aside those less fortunate and unable to pay.
But what do you do when the public sector labor aristocracy, through its unions, uses its monopoly to gain special privileges at the expense of the tax payer? Such as early retirement (age 52 for the SNCF train company), cheap subsidized housing, free services, special health care facilities, generous vacation and so on. This is what has French public opinion so angry. This anger is allowing the government to push through sweeping reforms which will lead to the partial or full privatization of many services and that, of course, is the end game.
