I did answer your question. As for your answer, well, the vast majority of people do not choose to stand on principle when faced with the likelihood of falling from a fourth floor window, falling into a death spiral of unemployment and homelessness that leads to freezing to death on the street or suchlike dire fate. You claim you would; the two obvious possibilities to account for your claim are:
1. You are a man of principle, to a degree that is highly unusual.
2. Your intuition, from a position of safety and comfort, about what you would do in dire straits, is inaccurate, to a degree that is highly usual.
The difference in prior probability of these two scenarios is equally obvious.
> If you were fired from your job tomorrow, are you really going to drop dead? I doubt it.
I already pointed out that much depends on whether other employers are offering better terms. But as for your question, actually there are many people for whom being fired is a life-threatening crisis. For many people, the expected timescale to find another job is somewhere between several months and never. If you've been unemployed more than six months, your perceived employability drops sharply. Many countries have an inadequate social safety net, such that long-term unemployment is likely to lead to homelessness, which is a life-threatening condition from which it is very difficult to escape. I remember one person who spent some time homeless and barely escaped from it, saying if it happened again he'd just commit suicide on day one and be done. That is the reality for a large percentage of humanity today, and in most developed countries it's getting worse not better.
