The date on the video is in mid-2011; I don't remember exactly what economic conditions were at that time, but I'm guessing there was a lot more gloom and doom (high gas prices, higher unemployment, etc) that may have led to such dire pronouncements ("the possibility of them being able to retire at 59 1/2, 62, is nil. Most people are going to have to work--if they have a job, that's a-whole-nother story--but they're going to have to work until they're about 67 or 70 simply to be able to get by").
Wonder what she would say now? I don't recall her ever touting EARLY retirement, just saving and investing for a conventional-wisdom "on time" retirement.
