I'm going with Reagan at the top of the list followed by Kennedy, Ike and LBJ.
Reagan presided over the most substantive changes to our tax code since 1913, put a stop to the cold war and elevated the USA to an undisputed leadership position on the world stage. He believed in American exceptionalism and got an exceptional America in response.
Kennedy was also a strong force in the "America is great because Americans are great" mentality and his push for space supremacy (even driven by ICBM research as it was) as well as ability to stand toe to toe with a maturing USSR was a boon to the American belief that hard work pays off and that the rewards of such work are much more sweet than that which is simply handed to you.
Ike and LBJ were successful but more along the lines of making national government more of a top down thing instead of a bottom up thing.
