Managing Democracy To Save Plutocracy

Paul Krugman claims that plutocrats only tolerate democracy when it can be made to work for them.  So how do the plutocrats make democracy work for them?  Krugman provides his list of tactics which have been effective for a long time.  He argues that underneath much of political and economic issues that we debate is the more general problem of plutocracy versus democracy.  The plutocrats are small in number but they are organized to protect their interests.  In general, they must convince others that what's good for the plutocrats is good for them.  They are pretty good at this game.
