&quot;Keynesian economics is fundamentally broken&quot;<p>How so, other than you don&#x27;t like it?  The data over the past 9 years seems to have confirmed a Keynesian analysis of the global economy.<p>&quot;but it allows the governments to spend as much as they want&quot;<p>No, that&#x27;s not how it works.  Keynes&#x27; theory is about how a general glut can happen, due to the role of money and bonds as a second and third variable in markets (vs the usual supply and demand curve).  There are various techniques to get out of it, the only time government should spend money is when we&#x27;ve basically dropped interest rates to 0% - free money! - and companies still aren&#x27;t spending it.<p>&quot;Furthermore, it devalues the money in our wallet everyday we don&#x27;t spend&quot;<p>You mean by inflation?  The inflation that doesn&#x27;t currently exist?
