I'm with you OP. The Cambridge's and in particular the Cambridge in-laws have cheapened what was already a difficult concept for modern times.
I think when the current Queen goes we should re evaluate whether the monarchy is relevant and fit for purpose going forward.
Prince Charles would be devastated not to be King but with the decision taken out of his hands he probably would enjoy a quiet retirement pottering around the garden like many 70+ year olds.
We could phase out the state up keep and gave them a one off redundancy style payment on a sliding scale of actual public works - Charles and Anne would get a bit more then lesser sums for William & Harry followed by much smaller amounts for Andrew and the York daughters hangers on the Wessexes and payments for these irrelavant 'royals' should be capped at about £150,000 like suggested for other public sector/civil servants.
The palaces and other property given over to National Trust or English Heritage or a newly created Historic building trust for us all to enjoy for a visiting fee.
They could buy what they wanted if they really wanted it from the redundancy payments and carry on raking it in from celebrity endorsements, book deals, party hats and paper napkins just like the Beckhams, the Rooneys, the Trumps and the Kardashians.
I think what is starting to grate on many is Kate, Carol, Pippa and the brother - the dad less so as he spends most of his time looking suitably embarrassed by the whole unedifying pantomime that the royal family is being turned it.
It really is now just scripted reality like Towie or MiC - 'The Brenda Bunch' would be a good title ... But instead of advertisers and the big business who benefit from them paying - we all are.
I don't think Kate deserves a holiday in Mustique at even 30p of my expense any more than you would think you should contribute to send my Nurse daughter there with her family. William, her husband is 'working' in the NHS yes, but any other NHS worker who took so much time off for extracurricular charity and family events would be sacked. It's not real. They are no better than Joey Essex & Gemma Collins. It's embarrassing that we are somehow meant to respect them.
By taking back the palaces, getting all of them off the books, reinvesting the profits from the property visits and land use we could make life happier and easier for many of our pensioners, or our cancer patients or maybe more of our children could go to bed at night having had a great day in an excellent school and a decent meal.
Let the Cambridges make their own way - they can then decide whether to have family snaps taken for a price to help support their lifestyle and if not they can use their private funds to sue those who breach their privacy.
And let the Cambridge in-laws fade back into obscurity - they have no talent, personality or interesting ideas that warrant continued public exposure.
