Do you tell prospective employers that you were fired?

I know that you aren’t supposed to say anything bad about a former employer, but what are you supposed to say when you were stupid enough to stay so long that their piddly 1–2 % annual raises turned into an actual living wage that they now don’t want to pay, but the company can’t admit that, so they manufacture another reason, and call it misconduct so you can’t even get unemployment? How do you spin that? How do you make it through an interview without crying? Hiring managers out there—does the lady who cries at the interview get the job?? I would guess not.
