Zero competent securities lawyers will argue waiving FINRA arbitration universally puts one into a more robust legal position.
For most Americans, it waives significant consumer safeguards and opens up realms of litigation tactics that are barred by industry rules but not law.
I am fairly certain that consumer and employment pre-dispute arbitration agreements are strongly negative but I haven't learned enough about FINRA/securities arbitration to have a strong opinion.
Sociopath structured parasitism always poses a liability around treasure. Handle or hire your own due diligence solutions... Seriously, don't assume either of our nonsense applies in your country. =3
