I was very lucky in the company I went to work for. It was a start up that no-one had heard of and I was given stock options to compensate for the a) not top of the range pay scale and b) the risk of moving there. I lucked out and the company became very successful so my options were worth over £1m.
Pretty much the same story for my dh, he was employee #6 in a company that was eventually sold to a huge banking conglomerate.
So, a combination of luck, stupid hours, ridiculous amounts of travelling.
We both still work now, albeit part time, because I couldn't NOT work, my brain just doesn't work that way. We don't really indulge in the lifestyle that we could, because neither of us grew up well off (although not poverty line) so we both struggle to spend money on stuff we don't need (except books in my case) even though we could afford it. We do travel well, but we have both built up such a stash of airmiles that doesn't actually cost that much!
My biggest luxury is not having to worry about money, if the kids need something we can get it, if the roof needs work, we can do it etc.
