Retired O-9’s probably get a decent pension. In the US and most other countries,I imagine they get by okay without Mom’s allowance. But he could always follow the American trend and sell weapons to the government after retiring, too.
I guess I’m not happy about seeing Charles not pass on some of mother’s money. If the queen chose to have multiple children, then it seems she has some obligation to make sure those kids are treated fairly to one another, without leaving unkind value judgements behind to scar them further. If she protected Andrew when she was alive (when she would have been better being stricter with him), then I think he has some points about being left stranded now. Additionally, it’s not clear that Charles will live for the 7 years it takes to make any money Charles passes on be tax free. So the longer Charles waits to give funds to his siblings, the more likely they are to pay big to inherit, where he won’t for himself. More family unfairness. In case I’m looking like an Andrew apologist, I think he’s guilty of everything he’s accused of, and has a rather disgusting personality on top of it.
