One of the ways forced arbitration benefits companies is that the individual being subjected to it knows their complaint will be decided by a kangaroo court.

They also know that any award they might receive will be smaller, and that if they do not win the case, the process will be costly and without appeal.

If the win rates remain unchanged after filtering out most of the consumer/employee complainants who don't have a slam dunk case, that is likely because there is systemic bias.
