"The airline system needs to be bailed out every so often so it is in the red."
Incorrect, the US has not bailed out airlines to any significant degree. NO COMPARISON
"Some major US car companies need bailouts, special tax breaks and other subsidies to survive or else they would be in the red."
You equate a once in a generation bailout of two companies, since repaid, saving tens of thousands of jobs, to the year-in, year-out major subsidy of an underused mass transit system? The California system will likely require 100% subsidies: It’s forecast (likely optimistically) to take in $33 billion, with a total cost estimate (again optimistic) of over $55 billion. Make that $30 B income and $60 expense (I bet it’s worse) and there’s your 100% subsidy. NO COMPARISON
“The highway system is paid for by taxes, otherwise it would not exist or it would be semi-public and semi-private and therefore “in the red”.” Uh, the highway system is paid for by direct use (fuel) taxes, and is therefore self-supporting. The only problem is the under-taxation of gas and diesel, resulting in the inadequate maintenance of this critical infrastructure. NO COMPARISON
"The US military is completely “in the red” by this definition."
Silly. NO COMPARISON
“Most farmers (agricultural companies) get subsidies or else they would be in the red.” Any facts to support this??
"Do you think all these things should not exist, therefore? Or do you think they all should “make money or break even”? I think they are all basic necessities of industrialized nations"
The creation of a new, underutilized, underfunded rail network is not a national priority, not a “basic necessity”, nothing like the necessary actions of government. NO COMPARISON
"…and other nations manage to pay for them, so the USA can too."
FALSE: these countries are nearing, or past bankruptcy: Portugal, Italy, Ireland, Greece, and Spain. Great Britain has riots over the spending reductions they’re being forced to make. Your ideal contries of the EU CAN’T manage to pay for them after all!
