This isn't strictly true.
The Companies Act 2006 section 172 covers the "Duty to promote the success of the company".
(Even in the US, it isn't true. There's a good Stackexchange answer on this that in have bookmarked somewhere.)
Making money is not mentioned.Part (d), however, describes a duty to consider " the impact of the company's operations on the community and the environment."
Corporations are obliged to make profit for their shareholders, so they can't do whatever they want.
Perhaps find a framework on a local scale that brings about positive change in your local community then find a way to scale that? It's far easier to solve lots of small problems, you can only focus on one thing at a time, etc.
