Not all roads were built originally with money from tolls. Many are payed for by the taxpayers. The road in front of my house, for instance. And the roads are maintained using taxpayer money.

All of the things I listed are examples of socialism. Any time money is taken from the citizens of a country in the form of taxes and is used collectively to pay for things that everyone has access to, that is socialism. It doesn't matter if it's federal, state, local, property, sales, or any other kind of taxes. It's all socialism.
