The RMT has been very effective in that regard though it shouldn't be considered as a purely good thing.
Part of protecting that privilege is making that job more valuable through scarcity (whether that be through restricting the number of drivers, imposing where they can strict regulations, striking whenever their hegemony is threatened).
This isn't always to the benefit of the paying passenger. In a lot of cases they actively makes things more expensive for all, as it is in the interests of their members, or cause huge disruption.
That is utter rubbish. The RMT does not, has not and could not restrict the number of drivers available to a TOC, and the regulations it "imposes" (or to be much more correct, "follows") are usually long established railway regulations that often have safety at their heart which the government and the firms are actively trying to get rid of - like the strikes against driver-only operation on Southern a while back, which were emphatically in the interests of the paying passenger (unless you think having a train with more than a thousand people on it with one member of staff aboard between stations is a good idea) as well as the employee (as the government weren't going to give them any more legal protection for the added responsibility they were told to accept).
