If you define “important problems” as problems that directly affect human welfare (hunger, access to important information, human health, economic opportunity/pursuit of happiness, public safety, military security), each of these have tens to hundreds of millions of people working on them every day. They are called farmers, doctors, nurses, educators, installation and maintenance personnel, sanitation workers, soldiers, public health professionals, caregivers, etc. Actual workers. If you mean “visionaries” selling self-serving snake oil solutions to what often prove to be non-problems or insolvable problems, there are rather fewer of these than workers directly implementing daily solutions. Thank goodness for that. If the visionaries had many years of practical hands-on experience solving day-to-day problems before proposing their broader schemes, more would bear fruit and more visionaries could be funded. But few want to do that preparatory dirty work. And those that have that experience are more valuable to society as managers of the daily work and generally lose their enthusiasm for the endless posturing that goes with high-stakes political crapshoots masquerading as “solving important problems”.
