In the UK, they are eliminating tax relief for private schools, so that's one. I wasn't aware that private healthcare receives tax relief. I've often felt it should be exempt from VAT because a lot of the people now forced to pay are ordinary people who can't wait years for treatment on the NHS - and they get charged 20% value added tax!

I didn't know 80% tax band ever existed. Not really worth anyone being in that tax bad so they can get 20%

Yes, I did think that the kinds of expeditions you were speaking of are now being privately funded anyway - Elon and Mars.
