I have gradually become convinced by mountains of evidence from many quarters that the Keynesians are right-- we are in a demand constrained economy. One of the problems I think is that economists and politicos tend to always be fighting the last war. In the late 1970s to early 1980s -- the last time the economy seemed this systemically bleak -- the problem was insufficient capital available for investment combined w…
My view on Keynesianism is that it's basically been bastardised to the point where it's unworkable. I say that because my understanding is that Keynes originally proposed a system where the government ran a surplus during the "good times" and then ramped up borrowing and spending during the "bad times". This actually makes a great deal of sense because during a recession investors are usually falling over themselves…
There are even good, clean, mathematical accounting truths behind this. If you sum up all monetary assets and all debts, the net must be zero just as a matter of accounting. So, if individuals are to build up savings (which most people would probably agree is a good thing), somebody else must go into debt. This somebody else could be private firms doing investment, or it could be government.
If you want government to be in surplus or at least netting zero as well, then firms must necessarily be in ever growing debt, which is probably just as unsustainable.
(Note that, as long as you look at a single isolated country, a third option is that foreign countries become indebted. But since we live in a closed system and the net over all countries is zero, this is not really a workable option either.)
