because they simply didn’t happen
They have. I have watched people walk on water. Of course, not in some magical way... all very explainable when you understand the underlying trick.
many people, including myself, have witnessed students acquiring skills and experience in school that they used to obtain jobs that provide ample wages
Likewise, simply watching someone go to college and get a job afterwards is not sufficient evidence that college is the reason for the outcome.
What we do know is that incomes have held stagnant through the rise of post-secondary schooling. This tells that some people always found higher paying jobs and other people always found lower paying jobs. What it also tells is that more people haven't found higher paying jobs after going to college. If the more and more people going to college were finding more and more higher paying work then the aggregate income mathematically could not be stagnant. But it is.
So, what you have is an extraordinary claim. Unless you just want to buy into a religion and believe everything you see at the surface level, extraordinary claims require extraordinary evidence. What controls do you have to ensure that you've not just missed an underlying trick?
