It pleases me that you play at breakneck speed, but your brain must be malfunctioning
It stands to reason that the same players on a design which is 7000 yards compared to a similar design of 6000 yards will take longer to walk. That is one reason for slower play today than in previous generations. There are other reasons of course. For instance,
100 years ago 4somes and 2ball play were more prevelant than 4ball play
Tees were closer to greens
Courses are generally are less forgiving these days and modern equipment makes it easier to find trouble even though it shouldn't if people played smartly...so in essence, user error
Poor tee time managment
Design not suitable for getting golfers around quicker
Stupid golfers choosing wrong times, courses and tees for their ability...also not properly understanding etiquette...this ties in with poor management
There is a divide between public golf and private golf in that the culture is often different on publics making it ok to play slower and it has been publics which are the mainstay of modern golf development
I also think there has been a general culture of slower play developing since Jack's early days, the rise of televised golf and the rise of money to be won/earned...watch the pros of today compared to pre-tv...not even close in terms of role models for speed of play
Much of the above can be explained by a large percentage of modern design not being best for the game and how it should be played, but what is best to make money or sell something uconnected with golf.
