>The solution I think should be something like governments borrowing money at the near zero rates we have at the moment and doing stuff like investing in infrastructure and things that will boost spending. When you get back to too much money chasing too few goods and inflation they can back off but we're way off that point in most economies at the moment. This is a popular idea but the problem is that in practice the cutting back never happens, so you end up with government policy together with central bank interest rates causing deeper recessions, or even creating the depressions they were intended to prevent.
