politics? I don't think so. Economic inequality is a very interesting social phenomenon, though it is often written about in a heated/political way.
Problems in politics have led to startups like Votizen and OpenCongress.
Where there is a problem there is a startup. And where there is a problem that people are willing to pay money for a solution there is a business model.
