On the whole I think rehabilitation is preferably to permanent incarceration, both morally and financially. However, you may be right in that the system may be flawed in that it assumes everyone can be, or even wants to be, rehabilitated. The trouble is, we do not have a process whereby someone can be ignored and labelled "not for rehabilitation". It is there for everyone, and people would probably lose those jobs or careers if they took the decision themselves that one of their charges should not be considered for rehabilitation. I don't know how you address that without changing the system, and individuals can't do that, it has to be a statutory change.
