Harper has a Master's Degree in Economics, he is brilliant.
Walker is not in Harper's league.
A master's in econ isn't that impressive........I mean, a BS in engineering is loads harder.
At top 10-15 US schools, undergrad econ is usually considered an equivalent to engineering, physical science, comp sci, and math because there is a very high degree of quantitative emphasis according to Wall Street Oasis. (At non-elite schools, it's sort of already at an in-between tier of difficulty between those and some of the more rules-based disciplines.) At the graduate level, that quantitative element is ubiquitous. The comparison you are making isn't really fair as much as you love your engineering.
Nonetheless, the argument was that graduate work in economics >>>> a 2.5 whatever in an incomplete Mickey Mouse stratego curriculum only done so that he could obtain power in a semi-meaningless organization. I don't usually believe education is very indicative of intelligence, but it should be obvious that Harper is very bright. Hard to tell with Walker so far.
