If they were real barristers they would get real barristers rewards.
Junior-doctors may carry out the some of the same procedures as doctors, but that doesn't make them fully qualified doctors.
At one time trainees in some professions, not only didn't receive a salary, they actually paid to learn, because the future remuneration was so attractive. And my recent dealings with 3 lawyers here certainly & eye-wateringly bears this out.
