The world definitely shifted about 30 years ago to placing much greater value on a college degree at a minimum and advanced degrees are often the entry card to success. Yes there are and always will be those without out higher education who succeed against the odds. But those cases get fewer and fewer. Even those with college degrees must commit to lifelong education. If you dont, you are not in the game and have to deal with what comes your way.
The days of going to work for a single employer with a defined benefit retirement plan and working there for 40 years are for the most part gone. The world moves at a very fast pace and you either keep up or get left behind. Those left behind decry the demise of those types of jobs but sadly they are lving in the past in a world that no longer exists.
