Likening the economic system to a computer operating system, Barnes (cofounder and former president of Working Assets Long Distance) suggests that Capitalism 2.0 has become obsolete because it damages the environment and widens inequality. He calls for an upgrade to Capitalism 3.0, the most salient feature of which is the institutionalization of a "commons sector" that preserves and enhances common wealth. Among the proposals proffered are a series of ecosystems trusts, a share per citizen mutual fund that pays dividends to all Americans, a trust fund providing start-up capital to every child, a risk-sharing pool for health care that covers everyone, a national fund based on copyright fees that supports local arts, and a limit on the amount of advertising.
