The main problem with utopias is that a fundamental requirement is that they be the perfect manifestation of an ideal. But humans have many different ideals which often cannot entirely coexist at a utopian level. Competing ideals must compromise, thus destroying the utopia. The best you can ever get is a society that deals with its diversity well instead of melting into chaos or oppression.
That said, history is full of people who put aside self-interest and preconceptions to try to move society forward. The first person that springs to mind is Florence Nightingale, founder of modern nursing. Her work establishing things like sanitation standards has saved untold millions of lives over the years.
