Random thought that just came to mind. Have coalition of debt holders (borrowers ) ever considered buying stock in these companies to influence them in the form of another company that is jointly owned or invested in by thousands or tens of thousands of folks?
Eg, mass activism campaign launches request for everyone to invest X% of what they normally would have paid into loans for the month (above the minimum thresholds of course), and/ or y% of disposable income into this fund. Now obviously one or ten people doing this will own just a few hundred stocks, but thousands doing this get tens of thousands of stocks-- thats when it could get interesting ;)
Obviously, would not be available to those really struggling under massive loan burdens and struggling to make every payment, BUT for those in the AND gate between reasonably high loan burden and comfortable income, which is a huge overlap with HN by the way, the impact could be massive.
In the end the results could be beautiful though: cannibalizing capitalism , - an inside job.
