I think that men of his generation just think that if a man is with a woman, he should just get married, regardless of the divorce pain that almost inevitably follows - from an age when the Blue Pill was considered to be normative.
it's a stigma from that generation to be their age and not be married.
Things may change but when you grew up with that mindset it rarely does.
Rupert Murdoch is 93 years old. He was born in 1931. His 1931 birthday would have made him older than some of the fictional Mad Men characters.
A 1931 birth year places him in the Silent Generation.
The Silent Generation was an interesting generation because some of its youngest adults were part of the Sexual Revolution of the 1960s. In the early 1960s, most of the Baby Boomers were still too young to be meaningfully affecting the sexual marketplace. A lot of later Silents (birth years 1940-1945) were attendees at Woodstock in 1969. The earliest divorcees of the no fault divorce era (1970-1976) were Silents as a lot of Boomers were either too young to be married in the early to mid 1970s or were in the earliest stages of their marriages and not yet dissatisfied enough to be divorced.
Not only is Rupert Murdoch a Silent Generation member, he's also earlier in that generation. Someone born in the late 1920s or early 1930s was more likely to believe in traditional marriage. Also, a blue pill ideology towards romantic relationships was more based in reality in the late 1940s - mid 1960s era. When Murdoch was a young adult, marriages were more likely to have worked out longer term than in later times.
Murdoch's first marriage lasted from 1956-1967. In the context of that time, that wasn't impressive. In more recent decades, an 11 year marriage ending in divorce is somewhat par for the course and actually a somewhat lengthy marriage. A typical marriage ending in divorce now is around 5-13 years. An 11 year first marriage ending in divorce is perceived much differently now.
His second marriage lasted slightly over 30 years. A 30 year marriage would be considered very successful if it ended with someone dying and was long enough for that outcome to be more realistic. One might think that divorcing at age 68 after a ~30 year marriage and a ~10 year marriage would have given someone lifetime exposure to marriage. Since age 68, Murdoch has now been married 3 times and also had one failed engagement.
I did not understand Murdoch marrying a past her prime Jerry Hall. Jerry Hall's best years were spent with Mick Jagger, as she was with him from her early 20s to early 40s and had 4 kids with him. Hall and Jagger never married. Marrying a nearly 60 year old Hall with 4 adult children isn't impressive for a billionaire.
