      Nicolas Dangond as noble as that sounds
      You must understand, High Quantity doesn’t come with High Quality
      If teachers were paid like NBA player or Surgeons
      We would have an surplus in supply of teachers that doesn’t meet the demand. What we really need is the equilibrium

    This is why I love 2011-2013 videos. They really put things into perspective. Not like today's teachers who are not at all practical in their thought process. I got some real Feynman feels from his explanation.
