Yes, it’s interesting, I think we all agree that by the time KC3 (77 years) and Princess Anne (75 years) are too elderly or unwell to carry on working as they are now, probably within the next five to ten years, a lot of pressure will fall on William and Catherine.
Prince George (12), Princess Charlotte (10), and Prince Louis (7) will not really be old enough by then to lend proper support, (George will be 22 years but could be in the forces or whatever, and by then it may be that the two younger dc are being guided to have proper, private careers if possible.)
So that is a lot of pressure on two people. And it’s not as if raising a family gets easier in the teen years, especially teens who are continually hounded by paps.
It is certainly going to be an enormous task for W and C to remain engaged as parents and “save” the RF at the same time.
So I can understand William wanting to take on a much more limited remit but I think it’s a really risky strategy if his assets in terms of grand estates and palaces, and his Duchy income, is not seen to vastly reduce alongside, and in proportion to, his work load.
That is why I think many people find it so puzzling that he is not prepared to publicly disclose the specific amount of income tax he is paying on his Duchy of Cornwall earnings, as King Charles is doing, as that would be a very positive signal towards future change.
In addition to that, as the late Queen knew, it’s a risky strategy to become less visible.
In summary, we don’t know yet how William will inhabit the role of monarch, but I predict that if he tries to do less, while holding on the same tax exemptions and vast property portfolio; then the institution is doomed.
