Had I known my career success would be the result of luck, I wouldn't have taken on debt as an adult to go back to school to get out of jobs like you listed.
Good fortune is why “back” was an option.
I am not saying that lucky people never work hard.
Or that success is entirely a matter of luck.
US Boomers had literally the world handed to them in the shadow of WW2 and therefore have no conception of the privilege into which they were born.
US Zoomers have assumed they're screwed and have given up all consideration that working hard has any sort of payoff.
In the middle, you find those who understand that success is borne of a combination of hard work, talent, privilege, and luck. Not any single one of the above.
