I’m a commercial lawyer, was a Partner and now work in a strategic/management role, husband works in IT for an investment bank, senior management level.
Amongst school parents we have lots of lawyers (solicitors and barristers, most were already partners or KCs when the kids were in Reception) doctors (mostly consultants before kids started), accountants and tax advisers, various senior front and back office jobs in City banks and trading houses, management consultants, venture capitalists, entrepreneurs (mostly IT ones), property developers, a journalist, an Oxbridge academic, a few media personalities, a personal trainer with a celebrity client base, a professional poker player, a charity fundraiser, a few senior civil servants. The vast majority of couples both work, are both high earners and met at university or work.
I’m not aware of anyone who is from generational wealth, but we are quite urban, no boarding and in the wrong part of London for really posh types.
