I'd bet there are trillions of chefs, speeder mechanics, plumbers, carpenters, architects, firemen, dentists, etc. in the SW galaxy, it's just that Lucas, Filoni or JJ don't have much use for them in their stories, so they focus on smugglers, bounty hunters or soldiers instead.
Sure, but such a heavy focus on bounty hunters doesn't seem to be something that a lot of other franchises do, aside from ones that are specifically about bounty hunters, like
Cowboy Bebop and
Killjoys (although both of those may have been inspired by the prominence of the job in SW). I guess it's a response to the strange popularity of Boba Fett, but it just seems an odd emphasis to me.
Speaking of emphasis, I continue to be interested in the implied racial politics of this show. While the Imperial characters are overwhelmingly white humans (even though a couple are voiced by black actors like David Oyelowo and James Earl Jones), the rebel characters in this show are overwhelmingly aliens or non-Caucasian humans. Ezra looks sort of Middle Eastern (basically a CGI version of Disney's Aladdin), Kanan looks kind of Hispanic (like his voice actor) or even Native American, Sabine looks East Asian (and has a South Asian voice actor), Rex is a clone of a character played in live action by a part-Maori actor, and now their new ally Ketsu is an African-looking character played by Gina Torres. They answer to Commander Sato, played by Keone Young, and Bail Organa, who's basically Latino (played by Jimmy Smits in live action, voiced here by Phil LaMarr). And the one major human character from the movies who's an ally of the heroes is the lone black OT cast member, Lando Calrissian. Well, we've also briefly seen Obi-Wan Kenobi, but as far as I can tell, he's the one and only white human character on this show who isn't a villain. Which is rather interesting. It supports the longstanding implication that the Empire was basically racist -- not just human-only, but whites-only. That wasn't really evident in the OT because virtually the entire cast was white, but
Rebels is certainly making up for that.
Of course, there should be humans of all ethnicities on the good-guy side even if the bad guys are all-white. And we've probably seen some white faces among the background rebel soldiers and pilots. But it's refreshing to see so much of the good-guy narrative being carried by people of color, and to see so much more diversity in this show than we've had in any prior SW incarnation.
