That looks like a biased source, concluding in the first sentence of its introduction that "pre-Dispute Arbitration agreements force people into a form of ‘Rustic Justice’ whose primary purpose to evade meaningful accountability for violations of contract or statutory rights" [1].

That said, I do know bank lobbying group who want to outlaw arbitration for unaccredited investors. Will pass this along.
