I don't buy the distinction between the discipline-subject and the achievement-subject. Our society runs very heavily on the threat of discipline, it's just naturalized and made invisible by a bunch of intervening social structures. And it's more invisible to some people than to others; if you're working a low-wage service job, you know that you're always at risk of being made homeless, lacking reliable access to food, shelter, and medical care, and subject to being brutalized by security forces. Even people who think they're driven by achievement may well just have internalized the threats to where they can't see them as external anymore.
I know nobody actually reads Foucault, but doesn't anyone at least read the Cliff's Notes?
