&quot;What can startups do to increase prosperity for everyone?&quot;<p>I think cheap quality housing is a huge area that would help everyone. Taxes and housing together eat up the vast majority of the earnings most people make.<p>What could make a difference?<p>- applying technology to building denser housing. for example, imagine cheap robotic excavation, so every house and building could bury all their parking lots and long term storage areas below ground instead of occupying valuable real estate.<p>- improvements in transportation. Making transportation faster and more comfortable means more people can affordably live within commute distance of prosperous urban areas (say, the SF peninsula)<p>- advocacy: pushing for changes to zoning rules to allow dense, livable communities, bringing more housing to our cities. For example, imagine turning a shopping center + parking lot into a pedestrian-only mixed-use urban area, modeled on the best dense cities out there (like Tokyo, Munich, Stockholm, etc). This requires a combination of property developers with a strong vision, changes to zoning laws, and a strategy for overcoming NIMBYs.
