Well, I was one of the lucky "rich private individuals" who was part sponsored. My "wealthy" dad had sufficient equity in his house to allow me to secure a loan on it, and in my "well-paid" graduate job, living at home, I managed to save the £5000 that I needed to start with over the course of a year. I was then made redundant after the course, with a £13,500 bank loan. Not helped by the fact that my wife had also had to spend £3000 to buy out of a house she part-owned before we got married, due to negative equity.
Rich private individuals, no. They generally go to merchant banks or set up their own companies. Motivated people who will ignore obstacles like an additional cost of £10,000 to achieve a dream, yes.
