those numbers don't mean much unless you also take into account the # of positions available.
Hey, why don't you add NBA stars to that list, I am sure their median salary will be at the top of the list. why doesn't everyone try to be an NBA star then?
a crude analogy perhaps, but it illustates the point that the salary number alone means nothing without considering the availability of jobs. we both know the answer as to why everyone doesn't aspire to be NBA stars - the money may look good, but only 100 jobs are available.
