The main difference IMVHO over the last 60 years is that up to around the mid 1980's golfers used to walk at a brisker pace between shots and generally had more consideration for other players in their group and on the rest of the course.
Observance of the HNSP on the tee and golfers 'ready to play' was also a given.
So much time is wasted by modern players faffing around on the tee.
One of the guys in the group I was playing in yesterday commented on this - bad enough players who take their time over every shot - but just as bad are those who just amble along - 50yds behind.
And as you say observance of the HNSP was something that speeded play us folk weren't having to be asked to move by the player about to tee off (but let's not go there...)
