I think the big thing is are those people wealthy themselves... Because I had a brilliant accountant for tax, but he also ended up struggling with money in the years I saw him. If they are living proof and walk the walk, maybe they know what they are talking about. Society is often full of negativity towards wealthy people and wonder what they did to get there (must be dodgy/greedy people) but they know something that we don't and we need to find great wealth mentors.
