Take a look at the medical profession to see what you're proposing. There's a higher bar of entry to become a doctor. There's also a ridiculous shortage of good doctors in the world. So we can continue along as we are, or we could try
to make medicine easier to practice so that we can try to lower the bar of entry without sacrificing quality.
Uhm, but by lowering entrance requirements, you're also reducing standards.
Even so, the academic rigour needed to read medicine at any of the redbrick or Russel Group universities isn't high enough to put people off, but quite frankly medicine needs the best of the best. (If the morality of the job doesn't attract applicants, surely
the £60,000+ GP salary will).
