Exactly, and the other thing I think is missing from the belief money is always more valuable than time is there is a scaling limit to money in most cases. In your example you go from x to 4x but taking a developer in London with say a new-senior salary of 70k for a standard low-medium stress role, (with a few exceptions such as working in finance) you might get up to 100k by making a change, which is ~1.4x. But that extra 30k is taxed at 40% so isn't significantly more and is irrelevant against the actual cost of housing in London. HN is always a SV bubble but by and large jobs that allow you to triple your income are vanishingly rare for the average developer, so given you're not going to change your situation entirely with an extra 16k why trade a known quantity for more stress, longer hours and a worse quality of life.
