Paul Krugman explains just how essential math is

Ok, in truth, Krugman explains that arithmetic and intuition are the gold standards, and that anything else is superfluous.

The takeaway quote:

A colleague once explained to me that the optimal amount of math for an economist to know is always, of course, exactly the amount of math you personally happen to know — anyone who knows less just doesn’t have the tools, anyone who knows more is excessively teched up. Hey, I think the kids these days are taught way too much math. Also, they should get off my lawn.
 

How true it is.
