Notail class leader application

How do class leaders become class leaders? how can the class leader change?

Class leaders become class leaders by waiting until the current class leader quits, is deemed unacceptable by today's standards, or most commonly is personally killed by the person who wants to be the next class leaders. Aka it works the same as notail O-classes, with the main difference being that it is WAAAAAAAAY more common. It's fairly rare for a class leader to rule past the 150-year mark as they tend to be quickly blamed for shortcomings of their class and it takes a good class leader to beat the odds and show off that they are a good class leader in trying times where the issues happening might not even be their fault!

(Aka, sometimes class leaders are used as scapegoats. In the case of the N class leader it's more like a sacrificial lamb....)

It doesn't help that if you want to be a long-term class leader you either want to be untouchable (Like the P-class leader who has been a leader for 1000s of years because most people do not physically know where they exist.) or a semi suck up. After all your fellow class leaders may start picking at you at any sign of weakness, but owing them lots of favors might make them look the other way.

Aka, it's all based on survival of the fittest.

(Note if a person kills a class leader they still have to show they're more than good enough for the job. If they fail they will be tossed on prison planet forever and the killed class leader's clone will be brought in.)
