No, the money we borrow puts money that is sitting on the sidelines into the real economy. The government can borrow at interest rates at or below the rate of inflation. In real term it's getting paid interest to borrow money. If it's invested in infrastructure that helps increase our future GDP potential, it's a no brainer. The alternative is paying people to sit at home and have their skills deteriorate. That is a guaranteed loss. It's not rocket surgery.
Well I'm definitely not supporting paying people to sit at home. Thats definitely a waste.
Exactly how much money is "on the sidelines" anyway? If this money was not spent on goods and instead saved wouldn't that just make it into the economy by banks lending out that money anyway? To companies etc?
If there really is all this money on the sidelines it should be easy for people to get money to invest in capital, open up factories for the unemployed people to work in.
Must be some reason why this isn't happening, too high minimum wage perhaps? Prohibitively high business taxes? Low confidence? All of the above? There must be some reason why China is cranking out so much while we are not.
