Questions that are rarely asked

In my email, from Eric Crampton:

Imagine the following deal, which is entirely not on any PPF so it’s not really a deal anyway. But imagine it. Genie offers a button. Push the button, and it burns the last n years of every journal in economics, along with all knowledge that those results ever existed, though they can be rediscovered. At the same time, every potential voter is brought up to a thorough Econ 101 level of understanding of Economics. At what value of n is the deal no longer worthwhile? A decade? Two?
