I recall a chapter that struck me from Bob Taylor's book (of Taylor Guitars). The first half of the book was all about him building guitars in a shed, then loading them in a car and visiting guitar shops one by one, trying to convince them to buy his guitars and display them next to the Martins and Gibsons etc. that had a lion's share of the market.
Many years later, when he became one of the most successful guitar companies in the US, he built himself a nice house, and he used to invite his staff around for an annual BBQ to show his appreciation of them.
Then one day, at the BBQ, he overheard some senior management pointing at his new pool rockery and saying "So THAT's where my bonus went this year...". He stopped inviting staff to his house after that incident.
"Tall poppy syndrome" exists in all industries and cultures. Personally, I don't see why people who have sacrificed a lot in order to make money in the early days cannot enjoy it later when they _do_ make it. As long as they maintained a high standard of ethics and principles doing so, of course.
