I have never worked in a job where you can give a reasonable pay band and routinely made 1.5-3x what other people with the same title did, before bonuses. This really only works for well-defined jobs in production, retail, and seems to bring little utility for the HN crowd.
The same work should bring the same payment, period. Everything else just ends up rewarding those with the best "negotiation" skill which is completely unrelated to one's actually work-relevant skills.
I once spoke with someone who acknowledged this, but said it wasn't a bad thing - if the market has decided that someone is worth less, why should he pay them more than he has to?
