Economics GOAT

This is a silly business, but as someone who has taught history of economic thought, I can't help but offer an opinion... or three. 

1. Adam Smith

2. David Ricardo

Tied for 3rd (alphabetically):

Kenneth Arrow

Gary Becker

J.M. Keynes

Frank Ramsey

Frank who? Look him up. As for Friedman and Hayek... oh please... Hayek wrote a very nifty essay that every economist should read; Friedman's inflation expectations stuff is important... the rest is ideology. If you must have a free-market economist on your list, Becker kicks both their asses. 

Malthus?! That proto-Trumpian pastor? Smith had already laid out the population theory and way better, and presumably somebody else preceded Smith.
