7. Surgeon
ForbesCase Study: Patrick Soon-Shiong
Country of Citizenship: South Africa, USA
Net Worth: $8.6 billion (£6.9 billion)
Becoming a surgeon is no walk in the park, especially when you consider the time and money you’ll need to invest in education and training. However, the silver lining is that you could start earning anywhere between £26,350 and £102,500 a year.
Some surgeons, meanwhile, make a hell of a lot more than that. Case in point: Patrick Soon-Shiong, who is known for co-discovering the orphan drug Abraxane and for developing the experimental Type 1 diabetes treatment known as encapsulated human-islet transplant.
