The things you believe are simply wrong. Endlessly repeating them does not make them correct. On your bold point above, in most cases, "more efficient" would mean not being built, because most road/highway/bridge/rail projects can NOT generate enough revenue from tolls to pay for their initial construction and upkeep. Not even close. The major facilities that are being leased to private interests in various parts of the country have already been built, meaning that the private interests are simply taking over management and operations.
You might say that they then shouldn't be built, but this ignores the dramatic multipliers that most infrastructure expenditures generate in the form of land development, economic activity, and jobs.
In short, your fantasyworld answer would result in a much less competitive United States, when every other economic power is investing (yes, investing) dramatically in precisely these sorts of facilities.
Stop thinking based on conservative talking points.
