Help carry the slack.
William is is a damned if you do or don't situation.
If he doesn't streamline the Monarchy, people will be dissatisfied with the current set up, especially after the flagrant abuses of the system.
On the other hand if he does streamline the Royal Family, there are far less people to do the work and the lack of engagement and the lesser profile publicly means people are disaffected with the RF and don't really engage with it anymore. The march towards a full republic speeds up.
But I don't see people ever really accepting B & E as future working royals now all the stuff about their finances is coming out, I don't think they can be rehabilitated.
