That's why I added the side note about hedging. If you're leaving because of a boss you're basically treating that person like poison. It doesn't really matter how they feel, because you don't anyone in your circles to touch them. You don't want future employers to talk to that boss. You're getting references from other relevant co-workers. I mean, even if you don't say "I'm leaving because of person X", there's a chance they know this anyways, regardless of what you say in the exit interview. At that point "how they take it" is irrelevant.

It's true, the OP could be from another part of the world. The goal with the US comparison was simply to provide a gauge that is not connected to a dollar number as that dollar number because less relevant over time. I am using the US as a baseline for this is the income difference of a typical family and this is a very relevant number for nearly every one in the current world's super-power. In 30 years the number ($50k) will be irrelevant, but the premise of one year's family income will still be relevant.
