Coming back to this because
@Hygro asked nicely, but, uh, "money" isn't on the list. So I'm left with a bunch of less-than-ideal choices. Let's rate them individually, as best as I can on an Internet forum:
- Media representation of your identity: I'm a straight white guy, so, uh, nah. And I'd argue that's a good thing. Definitely don't need more of it, there's plenty.
- Social justice education and the language to discuss power structures: sure, this'd be useful. I suck at theory, and I suck at relating discussions out of the pit of interpersonal relationships that makes up us CFC OT posters. But money would still be more useful for me.
- Advanced math skills: I went into software to avoid having to do maths beyond a certain point Still look at quaternions as something akin to forbidden knowledge. But my problem isn't learning things. I can pretty much learn anything I put my mind to. I could specialise into more traditional CompSci (and therefore maths) if I wanted to. I don't want to. Technically I guess this means I already have advanced math skills (at least compared to the average). I took maths further than the average, after all.
- An Armalite and counterinsurgency training: if I didn't have a family? If I lived somewhere else? I mean, sure, perhaps. But honestly, nah, the need for guns is something that would only be relevant in a different life. Martial arts and body training? Sure. But that's back to money.
So why is my answer money? Because my main boundary is time. I'm a full-time software developer with two young kids, financial pressure (even if I'm making enough to live on, we still need more sleeping space as the kids get older), and hobbies that I don't want to ditch (water polo, video games testing, and so on). Money buys me time. Money buys me things like a web presence (which makes me more marketable). It buys me more / better clothes (which are generally always last on the priority list). It buys me networking. It lets me give more away. All of this increases "power" in basic terms, both personally and professionally.
In terms of what I spend my time doing, "social justice education and the language to discuss power structures" is probably the most useful (specifically the latter part - I'm always looking to educate myself on the former). But then that's also time that I don't have.
