Yes indeed - please do not ask me how "Justice" can be found by getting the cleverest person you can get on your side according to the size of your wallet! LOL.
Indeed. That's a variant of a conversation I often have with my barrister daughter, in relaton to lawyers.
I think it fair to say that many lawyers, particularly barristers, regard their activities as an intellectual/academic exercise/'game' - which means that the most 'clever' (and hence perhaps most expensive) participant will 'win', despite without necessarily much consideration of what may be the actual 'truth' (i.e. 'justice'). It's quite common, 'after the event', to hear two lawyers discussing the question of which of their arguments was the 'correct' one (i.e. whether justice was correctly served).
However, I'm not at all sure that there is really any solution to this. Given that there very often are 'two sides to a story', someone has to present those 'two sides', and if some are better at doing that than others, it's hard to see how one can avoid them 'being more expensive' - if one can only afford to eat in the local 'caff', one cannot expect to eat as well as in a Michelin-starred restaurant
It's not only the lawyers, since juries sometimes don't help, sometimes returning strange and seemingly irrational verdicts. I can see an argument for getting rid of 'lay' juries, or at least replacing them with 'professional ones', but I also fully understand the reasons why such a change would invoke many serious concerns. In present context, I can't see how any jury (even a 'professional' one) would really be competent to choose between two contradictory 'Expert Opinions' - so, as you say, everything I've written above in relation to lawyers also applies to expert witnesses.
