Because obviously America needs zero improvements to its infrastructure. No high-speed rail, no electrical grid improvements, no roads or bridges, no fixing or improving the water system, no blue-sky scientific research, no teachers to hire to decrease class sizes.... NOTHING, YOU HEAR ME, NOTHING YOU STUPID LITTLE LIBERAL!
Oh, I'm sorry, I thought I was supposed to sound like an Austrian "economist".
This is a pointless straw man argument. No one is claiming we should never invest in infrastructure. Some improvements in infrastructure have value certainly. It depends on the specific project. Spending for the sake of spending is ridiculous though.
Actually, the Austrians basically do advocate that the public sector should not exist, and should certainly not be constructing infrastructure, because if it was at all worthwhile, someone would make a private profit off it and do it that way!
No god but Capital, say the Austrians, and the Market is His Prophet.
You are confusing Austrian economics with anarcho-capitalism. Many anarcho-capitalists subscribe to Austrian economics, but certainly not all Austrians are anarcho-capitalists.
