I think there are different life strategies that humans use. Some people need to survive based on skill more than others. The most obvious cases of non-skill strategies are the ones where people make a living based on having a certain physical appearance, or else live off of inheritance.
This might be controversial but I think rich and powerful people are usually skilled. The skill might be pretty far removed from the technical, of course. But I think I can safely say that most people don't fail upward and don't preserve or grow wealth when it just falls into their laps. The skill of investing well is really kind of a planning and information-processing skill. Society generally benefits from successful management of wealth at that level, even if we on the bottom of the pyramid detest extreme wealth of those on top.
Yep but there are strange undesirable characteristics that are being selected. Some of which we don't fully understand.
For example, it is my personal belief that there is a selection mechanism for high suggestibility (by social media and search algorithms which can monetize it). Basically suggestible people are helped in their careers because they act like a money pipeline which redirects money they 'earn' back to social media companies. Social media companies might be thinking of people as straight money pipes leading outward vs bendable pipes potentially leading back towards themselves. Which kind of pipe would they select to pump money through?
This has a side effect of creating strong social alignment over bad ideas. If you empower suggestible people to make decisions, then whoever is above them can bend them in any direction they want.
