Mr. President, forget the wall.  It won't solve the problem.  A better approach would be to help them eliminate their drug dealer problem with a military intervention.  The Mexican people will cheer us in the streets after we liberate them from their corrupt government and replace it with one that shares our mutual values.  Of course we can't provide this service for free anymore, so we'll have to take their tequila as payment.  Are you listening to me Mr. President??  But don't get too ambitious - we can help the other Central American countries a little later.
