I don't work in tech, and hopping jobs will get you 5% at most, usually. Maybe it's because I'm in the public sector and wages are public information? Either way, it always comes across as VERY out of touch when people here talk about massive increases just by changing jobs.
Not to mention how casually they talk about changing jobs. As though there weren’t pressures (and desires) keeping people at one workplace, and that those people form a large enough percentage of the population that their resentment of inflation has political force.
