Smart libertarian guy meets smart occupy lady

I have often mentioned how much I enjoy Russ Roberts' weekly econtalk podcasts.  Russ is smart and a terrific interviewer.  This week he speaks with Cathy O'Neil.  Cathy is a mathematician who had a career doing financial modeling on Wall Street.  She became disenchanted and got active in Occupy Wall Street. 

On how much would you guess these two agree?  In the podcast, my judgment is that they are in agreement about 90% of the time.  It's a subjective judgment by me and the ratio could have changed had they gone on for another hour or so. 

I prefer to think that it is their common denominator of smarts and decency that did the trick.
