I think point 1 is largely that business/econ isn't needed, however a large part of econ is dealing with data sets. Regardless, college isn't a tremendous metric of ability; how many times has the fallacy been sold that it doesn't matter what you graduated in, just that you graduate? Programming and comp sci are largely about logic, and teaching oneself how to program is certainly a fine suggestion but it's not a very efficient solution for somebody who has previously demonstrated aptitude and is still going to face a learning curve once employed.
Stepping away from the startup scene and simply looking at businesses in general, it's ridiculous to think that an employer would hire you and put you to work with no training. Also a hire should be a long term strategy, turnover is very expensive and destructive to company culture.
"Building something" is a relative idea. Aptitude is not. My story isn't specifically important, just that hiring is maybe overly focused on buzzwords and the short term. But I don't know.
I may not be applying to the easiest jobs to get but I'm finding it incredibly difficult to even get an interview. After graduating from a top 25 undergraduate business program in 2 years and then going on to earn my MA in econ in another 2 all the while playing Division 1 football I thought it might be easier than normal to get a job. Ideally I'd like to be at an audacious startup and even rode my bike 215 miles to a midwest tech event (http://goo.gl/JX1ud). No such luck, unemployed as ever.
On a positive note, it's my opinion that energy prices are a better indicator of economic growth than interest rates and energy prices should continue to fall for the foreseeable future. The only problem is how quickly the economy will artificially inflate after years of QE.
