However conditions may be, it is certain that no manipulations of the banks can provide the economic system with capital goods. What is needed for a sound expansion of production is additional capital goods, not money or fiduciary media. The boom is built on the sands of banknotes and deposits. It must collapse.
-Mises
The same thing applies for government. Government cannot create jobs. It can choose to get out of the way of productive people, or it can pretend it's meddling in the economy creates value. But government fundamentally cannot add the value which is fundamentally what an economy is. Voluntary exchange of value for value.
