Our roads, schools, and public facilities are decaying just fine on their own with your sainted and bloated government workforce; especially in areas where Democrats are in charge.
Public employees are no better or worse than those in the private sector. In a macro sense, both contribute to the economy, keep money flowing.
You obviously can't back up the claim that deterioration of public facilities is worse overall in areas under Democratic leadership, but it's easy to back up the claim that red state welfare amounts to a form of extortion, and a primary source of their governmental incomes.
