What does "the climax of misery is to have to pay in order to obtain justice" mean?

In the past, laws were made not to foster equality and peace among people, but rather to exercise unbridled power against those who cannot comply with the terms. Inequality was palpable which meant that the law would only serve its purpose if one had the means to pay for it. The transgressor who came from a wealthy family was not castigated for his wrong doing, but a poor man underwent legal penalty if ever, adding insult to the injury. The justice system before squeezed them out until nothing was left of them. Therefore, the phrase "the climax of misery is to have to pay in order to obtain justice" meant that no one will give a poor, injured man a due process which is supposed to be his right as a human unless he pays money to the judge and his clerks.
