. >> let's go back to paul irvine. did he ever publicly apologize for getting it wrong? or did he just cut the check? >> he cut the check and he claims -- actually, i saw him the other day. he said, i wasn't extreme enough. i am still right. there is still time to repent, i guess. >> gail pulley, final question, a little selfish exercise. you were born in 1955, i was born in 1960. how has our economic world changed in our lifetime? >> well, if you go back to 1960, we can do a trend line. we are drawing -- i am 60 years old. every 20 years, my life has doubled. on average, my standard of living has doubled every 20 years. i went to two to 4 to 8. i am really eight times better than i was in 1955. if you think about your life, what did you have a 1960? you've got at least eight times more today. you really do. you know, i show my students this and i say, well, what did you pay for this? i paid $600. and i always ask them, what would i have to pay you for you to never use this again? that's really how much evaluate. i was guessing they would do it for less than 5 million. y
