In threads discussing career paths there seems to be an implicit assumption that everyone has agency and the ability to make their own decisions and results are simply a matter of choosing the right advice to listen to and doing the work you need to do at each step of the way. If we were discussing career paths in the context of wealth the assumption would be that nobody has agency and everyone is just a product of the environment they were born into and what you do is predetermined. So which is is guys? Can we actually choose are own career paths or are we just pissing in the wind here?
