Is the fact that starting your career in San Francisco nets you better offers elsewhere in the future a valuable statistic? There are a lot of top tech companies there and so presumably luring people away from them costs companies in other locations more money. I feel like this stat is really just saying work at a good company and then your next offer will be a lot higher
