Here's the think that the government and media do not get. Barristers and many other professions have had their wages frozen/cut since 2010. When professionals look at what their pay should be had it kept up with inflation, versus what they actually get, they are naturally pissed off. So the starting point if a feeling of grievance.
Now with inflation expected to hit 11%, and pay rises being offered in the 3% range, the issue is exacerbated.
Do the government care? No. Just keep telling folk that barristers, doctors, head teachers, train drivers etc. are "well paid", as code for they should shut up and go back to work.
