People like you seem to believe that what someone did 20 to 50 years ago grants him some sort of wisdom. That is not the case. What you have is wiss-dumb not wisdom.
Sadly, it appears you are thoroughly indoctrinated.
Here are a few rhetorical questions for your consideration:
Are there people in your life who urge you to forget everything you learned in the past 20 years?
Are you familiar with the concept of "continuing education"
More generally, how much of the world or even the U.S. have you visited on your own dime, or by your own labor?
