That's a very interesting perspective. Personally I thought Finn was the most "normal" character in that film (meaning the one most like us). He's just a child soldier that not only found a way out of it but he worked his way to the rebellion, with no "destiny" or the Force.

IMO he doesn't have to be rich like Lando or powerful like Windu. He just has to be cool and portrayed positively, and I think he is. If he was like Jar Jar then yes, I'd complain.

Either way, we went from tech diversity to Star Wars, so maybe we should stop here :-)
