Agreed.  Funny you should mention it.  We were discussing just this issue in Socratic Economics XI National Accounts a week or so ago.  I inquired as to the financial prospects for a from scratch recreation of the General Theory that adapted it to the global economy.  Mig thought it would be a cult classic and said:

Why do I suspect that if you were to write such a work you would find yourself practicing economics from Finnigan's Cave?  Or are there still more sinister methods of enforcing "market discipline" on the recalcitrant?
