"whereas paying for the right QC"
Just because the system became dysfunctional and the phrase "Equality before the law" became even a bigger joke. When money can buy sentences, what you get is the actual mayhem. Tell people screwed by Equifax, for example.
Anyway, far from big legal issues, we are often forced to hire a lawyer for silly stuff just because the system became even more dysfunctional, and lawyers understood they can profit greatly from it. Having a lot of lawyers among politicians does help. There are people that are ruined by legal expenses because someone with bigger pockets can bully them easily.
So if anybody can profit from stupid lawyers, they just work the same way lawyers do. It's just a pity they can't establish minimum fees and prices like many lawyers associations do.
