why do these families keep hiring Ben Crump??

[UpThruDere]

They don't hire him, he sees the signal, uses his fame and hires himself to the case.

 

[North of Death]

His job isnt to get justice its to settle

 

[Wiseborn]

Cause he takes his pay at the backend.

Also although he doesn't get justice he does get the bag so he has his worth. He also gets media attention.
