And in the era of greed, 80s and after, how many generations of trimmers had a shot at these cards before the motivation to trim went supernova with the rise of PSA, SGC, and BGS?

It's a very high number but no way is it 50 percent. Not even close in my opinion. Look at ebay, look at 707's store for a good sense of the distribution of graded vintage cards, most cards are still worth relatively little.
