I have a right to earn a living. I have worked many years preparing to do so in a particular area of trade. There is a market price for my skills. Taking 25% of that away is unfair, is my point. Justifying it by saying "Oh, but you could travel!" is the same level of empathy as saying "Let them eat cake".

You can easily make half of your original salary back by working part-time in a sector not directly related to the one you left. If you're already given 75% of your old salary, you won't even need to be picky. You can learn new skills and work on your hobbies/the rest of your life, while receiving a princely sum for the amount of work you're actually doing. It's only a bad deal if your current sector is all you ever aspire to work in, and I'd posit that's not the case for the majority of people.
