By worthy position I was thinking of something as simple as "not a temporary contract", I wasn't clear on that, my bad.

And I confirm my previous statement, the immense majority of people who go on to take senior positions, particularly at big institutions, are made from day zero.

That is an extremely cynical view, and it does not fit with reality. There is no mechanism where little Timmy gets a free ticket to be a university professor in science.

People who manage to make a career in science usually follow a specific educational path that includes a phd and postdoctoral research. No one would claim it is completely fair because there are many things that can block or hide that path (family situation; life events; lack of encouragement from teachers; being born in the wrong country; etc.). However, the system does not otherwise care about your background in any meaningful way.

You should consider the dark implications that you may be pushing misinformation that could discourage people who are gifted or intellectually curious and motivated from trying to improve the world by doing science.
