A good DCI technician will, over the course of his or her career, save thousands of lives by preventing DCI failures in the ships upon which he or she works, and will be rewarded with a comfortable salary, stock options, and free travel vouchers on participating starlines.
A good pure researcher will, over the course of his/her/its career, get published a few times, see his/her/its work plagiarized, stolen, or otherwise borrowed by the commercial sector, and will be rewarded with an increasing sense of bitterness as he/she/it watches the Universe continue to spin down entropically in several senses of the word. We should not, therefore, blame the pure researcher for being an elitist jerk. It's some of the only pleasure he/she/it will derive from the quest for discoveries untainted by practical application.
