You even see in this thread how people within tech but unable to pull FAANG salaries see this story as impossible. It's one viewpoint to think that it's possible for everyone to become skilled enough to work at a FAANG-like job (including passing the interview); probably correct so some degree. It's another (less rational) to think that every software engineer can work at FAANG-like jobs simultaneously; there just aren't enough positions.
This gets even more dire outside of tech. What job are you going to switch to every 3 years that nets you a 30% salary increase? If that kind of opportunity was wide-spread, there would be a lot less income inequality (or at least more social mobility).
laughing my ass off ... I expect the successful first and formost to share their success through actually paying taxes - then we can talk about their advice which won't be useful for the majority anyway b/c success in monetary terms is always defined by being focused on a minority.
Ideally yes. Though IME often the advice isn't applicable, so beyond a few fundamentals they break down. For example I cannot un-have kids, and getting a master's or doing a startup on the side would basically require neglecting them for too long. (Or quiting my day job and burning through our savings.) Lifestyle advice like modest living or moving far away also requires buy in from an SO or a painful break up/divorce. It's also a risk since they may change their mind early in the plan. Or they may decide the outcome wasn't worth the sacrifice and want to (or you to) return to the grind.
The immediate leap to discredit the success of others through assertion of privilege seems like it would discourage doing well.
A better solution imho would be to celebrate success but to also encourage the successful to share their insights with others so as to spread the fortune - much as the author of this post has done.
