You’re right that the draft is unfair, and not a perfect solution to the problem of marginalized people ending up in the military much more than privileged people.
Probably something I should have mentioned up front in this discussion is that I oppose the US military because I oppose imperialism in general. I don’t actually think anyone should serve, this discussion is more of a thought experiment to consider the implications of our current trend of liberalizing military service - letting african americans serve, ending the draft, letting non-heteros serve openly, and now letting women serve in combat could be seen as all part of the same trajectory, and I question whether it’s actually a progressive thing, or just a way to facilitate more efficient and cost-free warfare.
the idea that current enlistees are 'slaves' is an insult to everyone who ever endured slavery
Well, I didn't bring up the slavery metaphor, you did. I assumed that you were referring to the idea that once enlisted, the military has the power to control almost everything about your life, including whether you live or die. Which is reminiscent of slavery in some ways, though obviously not all.
But instead maybe you were just saying that during a draft, a government order decides who gets enlisted, whereas now it’s decided by the imperatives of the market. In other words, when the government forces you to work it’s slavery, but when the economy forces you to work it’s free choice. This smacks of libertarianism, but I don’t really care to argue the semantics of “slavery” anyway, so I’ll leave it at that.
Anyway, all that is to say that it’s mistaken to believe that our current military is a voluntary project. I mean, imagine what would happen if civilians stopped signing up to go to war. Would the government just shrug and say “guess we can’t do war anymore”?. No, they would increase the regulatory, economic and social pressures to “volunteer” until finally enough people did. Or less theoretically, look what happened when the US ran out of volunteers during the Iraq War: they conscripted people through stop-loss.
That’s a good example of how our military is still compulsory, just through different methods. And because those methods are more subtle and less controversial, they allow the government to wage virtually continual war with minimal political cost. Since political cost is one of the only forces capable of reigning in the US war machine, it’s a bad thing that the government has figured out how to minimize it.
I want to minimize the death and suffering caused worldwide by the US government. That’s definitely a political goal, but I don’t think it implies a cynical or trivial motivation.
