That couldn't be more stupid. There's a very simple reason why startups target rich consumers - it's because they have money, and without it, resource constrained startups die. Important problems are for NGOs, national governements, hundred billion dollar universities and international organizations to solve. The very reason problems so important still exist is for the fundamental reason that they require huge amounts of resources over many years at little to no return on investment to the business. Going after "important problems" as a startup is a very fast way of becoming bankrupt.
