“every citizen has the right to justice but access to courts is difficult for majority of citizens” why?

Because in my view ,the lawyer are of different view and of different type.The laywers take a certain amount of fees for the works they do,even if they win or lose the case of the individual .The fees of the laywers is most can't be affordable by normal middle class people which is bad for citizen to get the right which should be of every citizen of the
nation .

In another point the lawyer manipulate the truth that the lie seems like the 100% accurate truth.So it's hard for citizen to get the justice they already have right to.
