Keynes would have written the obituary long ago on Keynesian policy'theory as it has evolved to provide justification for a Fed and a Congress completely out of control. It has been bastardized to support empire building by a power hungry elite. This was not what Keynes wrote about in the General Theory.

We are in a difficult situation but I believe we can get out of it if we give ourselves time and stop over promising and put in place sensible policies. The key is whether we have learned from our mistakes. To start with there should be no spending initiatives unless there is matching funds to pay for them - including wars. Forget proposing any willy idea that gets votes.
