Yea, comparing achievements between generations is unfair: each era has unique challenges and opportunities. Crucially, within each group, some stand out for decisions and efforts that are different from the average. I am interested in knowing what people in my situation -age, location, context- are doing to improve themselves. If companies like Meta have detailed data about us, there should be anonymous and transparent access to understand what ‘people like me’ are earning, saving or achieving. Without that, comparisons are superficial. I want to know not just how much someone earns, but how they achieved it, so I can adjust my actions, not just my expectations. I understand they sell access to large corporations through an API, which is the backdoor you refer to. What is clear to me is that airlines make use of all that information, they know in advance who is coming on a certain flight and the possible presence of that person as an undesirable.
