A sound tactic but there's one issue: high-paying jobs, in time, often turn into a sort of "golden cage", which makes you unemployable and vulnerable to lay-off

A sound tactic but there's one issue: high-paying jobs, in time, often turn into a sort of "golden cage", which makes you unemployable and vulnerable to lay-offs. Anecdata: A friend of mine worked in banking where the pay was amazing, but the tech used mostly outdated(think Java 6 in 2018). At some point he got fed up with all that and tried to switch roles, but to no avail, because no one would hire him. He's still there but should a recession come he'll be in a very tough situation.
