In the 1975 video (https://www.youtube.com/watch?v=GO3ARNNSfKk&feature=youtu.be - around 1:40) they have the temerity to question the motives of those who sold their houses as if these ones were misguided. They really should have the quote from the 1974 KM on screen at that time...
"Yes, since the summer of 1973 there have been new peaks in pioneers every month. Now there are 20,394 regular and special pioneers in the United States, an all-time peak. That is 5,190 more than there were in February 1973! A 34-percent increase! Does that not warm our hearts? Reports are heard of brothers selling their homes and property and planning to finish out the rest of their days in this old system in the pioneer service. Certainly this is a fine way to spend the short time remaining before the wicked world's end." Kingdom Ministry May 1974 p.3 How Are You Using Your Life?
