Just ask businesses whether they would like to be run by instant polling of their customer base and see how fast they say no. A better approach is fusion, or cross-nomination, which allows two or more parties to nominate the same candidate on separate ballots. The Populists and other parties used fusion to great effect in the 19th century. The major parties responded by outlawing the practice almost everywhere. While the Supreme Court recently upheld the right of states to ban cross-nomination outright, the Internet process is far more compatible with approaches like fusion than with the current system.
Fusion can break the stranglehold of strict party lines.
A massive paradox plagues contemporary economics. On the one hand, we insist that macroeconomic growth demands increases in productivity. On the other hand, at the microeconomic level firms try to raise productivity by reengineering to reduce employment, which then affects the macroeconomy by reducing unemployed workers' ability to consume what has been produced. In the past, increases in productivity did not lead to overcapacity because foreign markets could be found for excess goods. National economies were open systems that could export.
