From a leftist perspective, it’s beneficial to have something like a draft because it forces all classes to confront the reality of our wars. Instead of how it is now when it’s mostly the lower class that goes to war.

The last draft we had was Vietnam, which was a PR disaster for the US military because middle class america saw (and experienced) the war for what it was: destructive and unnecessary.

I guess the difference is the sprinkler fitting industry doesn't result in hundreds of thousands of civilian deaths the way a war does, so I don’t really care how the general public perceives it.
