This week on the ProPublica podcast, reporter Jake Bernstein answers readers' questions about the investigation he did with Jesse Eisinger on how Wall Street bankers created fake demand in the run-up to financial crisis, increasing their bonuses -- and ultimately making the crisis worse.

Bernstein discusses whether this was all legal, how the rating agencies failed to flag the self-dealing, and how it all contributed to the banks blowing themselves up. Eisinger and Bernstein also responded to readers' queries in an earlier post.
