Royal Sticker Shock?

The Royal Family is worth $88 billion according to Business Insider Magazine.

The "Sovereign Grant" for 2019 (that is, the money the British taxpayer pays directly for the Monarchy) was $104 million (admittedly small compared to the almost 900 Billion pound British national budget).

The Queen alone is, as at 2016, worth $530 million.

The Prince Harry and wife are worth $30 million.

Now, why does the British taxpayer pay anything to these people? Or, shall we say, they might dip in to their champagne budget and pay for some of their "grant" themselves. Or maybe they're an amazing bargain. But with 210000 British children going to "stuck" schools, one cannot help but think that 100 million might have gone a long way to getting them unstuck...or maybe it's hard to blame any of the so-called budget shortfalls or for anything or policy failings on the Sovereign Grant (roughly barely 0.1 % of the budget) and rather blame bad government and politicians.

The thing that I do not understand is: what do two people who have $15 million each need with any family support payments? (Hell, they could even provide themselves with their own protection on that allowance)

PS and to Repeat - the Royal Family is worth collectively the rough equivalent of 10% of Her Majesty's Government's annual budget! Sheesh...but I am still a Monarchist.
