I can't edit my other reply so just going to do a new one.
One of the biggest eye openers I had as a developer and how I was being 'exploited' was when doing work for a consulting firm, the ceo of the company asked me to pick a open source app, change the logo and a few other things (2 days work), and the next day he presented the app as one of his 'business solutions' to some big shots (talking airports and big media companies) and was able with that to sell around 1.2 million euros in consulting services by demoing the open-source app and claiming a lot of the credit for that app. This is something as a developer I still cringe and would probably feel like I would need a bleach bath to clean myself but seems to be day-to-day from people that have MBA's or business/finance education.
I'm not complaining about my career by itself (I make good money), but it is still quite a few magnitudes lower than what I see my peers in business/finance making around here, and to top it off, seeing how their networks work is also something most developers never would think of using/tapping into. From easy entry to schools for their kids, to privileged access to clubs and activities (sorry, I don't know the correct translation for what I mean)
