Inequality and poverty are suddenly hot topics, not only in the United States but also across the globe. Piketty, no Marxist, says a solution lies in a “confiscatory” tax on wealth: Tax salaries over $500,000 at 80 percent worldwide, and tax wealth at 15 percent worldwide. And fortunately, others have been digging deeply, thoughtfully into the same questions, and they have some practical as well as achievable ideas for reversing poverty and inequality trends. Like Smith, Alperovitz asks a question with his book’s title: What Then Must We Do? Not just food co-ops but also agricultural co-ops, electric co-ops, insurance co-ops, retail co-ops (such as REI) and retailer-owned co-ops (such as ACE Hardware), health care co-ops, high-technology industry co-ops, artist co-ops, and credit unions.
