Here is a riddle. Who said this?

"It has been more than four years since the US economy first entered recession—and although the recession may have ended, the depression has not. Unemployment may be trending down a bit in the United States (though it’s rising in Europe), but it remains at levels that would have been inconceivable not long ago—and are unconscionable now. Tens of millions of our fellow citizens are suffering vast hardship, the future prospects of today’s young people are being eroded with each passing month—and all of it is unnecessary.
For the fact is that we have both the knowledge and the tools to get out of this depression. Indeed, by applying time-honored economic principles whose validity has only been reinforced by recent events, we could be back to more or less full employment very fast, probably in less than two years. All that is blocking recovery is a lack of intellectual clarity and political will."
