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.
I wrote that page after reading every one of those sources. In full. Including all cited supreme court cases. I actually initially felt that mandatory arbitration was fine and somewhat pro consumer. I changed my mind as a direct result of the research.
To the extent possible id like to strongman arbitration but need to find sources.
Curious who that lawyer is. Because for financial arbitration, the win rates are ridiculously skewed in favour of borrowers and retail investors.
