Ah, but you are forgetting that not all rich families are the same. Looking at Zaun, I get a feeling of a society that was once very traditional, but a large industrial boom pushed resourceful people or CEO's of rapacious companies to the "top of the food chain" while the previous high-class families fell into shadow. Perhaps many even fell from grace. They're a dying class.
The detail that I always look at, is the fact that Viktor had a private laboratory even before he locked himself away and started self-augmentation. He had money. Or his family had money.
Let's suppose his family belonged to the higher class, the type that is now relatively rare, as the top is being overtaken by first generation rich. I doubt they would meddle with them (going to their organized parties, or whatever), they don't think highly of them. That's what happened in the real world as well, if I'm not mistaking. They're not very social, they're conservative even though they're dying out, or exactly because they're dying out.
Another thing is the Prestigious College of Techmaturgy. I doubt anything in Zaun comes for free, even if you're the best at what you do. The other possibility is sponsorship by some company, but I believe that in Zaun, after you finish college, you're then a slave to that company.
Viktor had enough funds to start the entire Evolution. Equipment and materials for that are far from cheap, and I find it highly unlikely that someone funded him while he was locked away, while seen as a failure that "tried to steal Blitzcrank from professor Pididly".
He acts purely in his self-interest, experimenting as he sees fit regardless of the impact it has on society.
I thought his goal is interesting exactly because it is extremely focused on impacting society as a whole? "Join the glorious evolution".
