Perhaps not phrased well enough in my post, but as I said, my personal take is that - so long as the quality of access to justice can't be fully separated from wealth - third-party funding of lawsuits should be allowed, just not in secret. For an immediate fix: have parties disclose any third-parties funding their suits and any conflicts of interests they might have with the opposing side. Make the judge and jury aware of this and document it in the public proceedings of the suit.
