Actually I care. Because what I think they are attempting to do is morally wrong. They want all the privilege of being royal but none of the work or constraints that go with it.
As much as I understand and agree their security should be paid for, it's required and I think too much for them to bare alone, I think it's too much for them to ask for a grace and favour house in the uk, frogmore, and for the gueen or Charles to continue to pay to run their offices and home costs, they are worth 34 million for goodness sake. They should be financially independent already. Not at some point in the future.
They also should not be able to cash in on their titles. Any attempt to do so, should see them stripped immediately of them.
If they had said, we will live as private individuals, not take paid work, and work on charity, and have our security and costs paid for by the queen/Charles, then ok, I'd get it. But saying I want it all paid and Any work I do I shall be paid for, and I'm going to use my title to get that work, then it's very morally wrong.
