Hugh Segal has been on The Agenda many times, talking about why, as a conservative, he favors the creation of a basic income program for people experiencing poverty. What he hasn't discussed is how he came to that position, thanks to his own hardscrabble upbringing in Montreal, as the son of a cab driver who died when Segal was just 14 years old. He talks to Steve Paikin about his experiences, the topic of his new book, "Boot Straps Need Boots: One Tory's Lonely Fight to End Poverty in Canada."
