I would leave if my lord wasn't providing me with a reasonable tax share. I tax my knights at 15%, and am about to drop it to 10%.
The idea imo, is to encourage knights to come to my region, not encourage them to leave. I want my knights to have as much gold as possible, so they become loyal knights. I don't need gold, I need knights. They are more important in general both for me and my realm.
Personally I think arguing that taxing a certain percentage is bad, that just means the other person is greedy. It shouldn't be about how much you could receive but how much you are receiving, IMO. (That is not supposed to be an insult if it sounded like one.)
