As far as Germany, borrowing money only delays the problem, not solve it. Now if you can borrow and produce enough income to pay back both the principal and interest from earnings, yes borrowing might have helped. But Germany was hopelessly in debt with no growth prospects that could ever pay it off. Kind of like the USA and most of the rest of the world is right now.

Keynes and the Austrians part company pretty quickly. Yes, if they stimulated only in bad times and ran surpluses in good times, theoretically it should work. But it still does not eliminate the boom/bust cycle of a flexible money supply where it expands too much in good times and contracts in bad times. The Austrians think it is better and more natural to let the business cycle burn itself out early from a lack of liquidity (easy money via fractional reserve lending) than let it expand to colossal levels. And that is what government involvement trying to tweak the system does. Makes the highs higher and the inevitable lows lower. Everyone likes the credit induced highs, no one wants to pay for the party or have the hangover. So we get easy money. But the growth caused by it is a mirage. It only creates faux growth where industries over invest because of phantom growth brought about by the easy money. When the easy money quits flowing........................ well we get what we got or at least what we are about to get. A re balancing of debt, either via defaults or the destruction of the currency.

So to the Austrian economics way of thinking, Keynes is nothing more than a glorified Berny Madoff. A Ponzi Scheme that has to eventually fail, either voluntarily via contraction and defaults or by the ultimate destruction of the currency.

So your and my thoughts will probably never gell concerning Keynes. But he did say some smart things about inflation and gold.
