If we think about citizens as shareholders of a government, we as citizens don't possess the same feedback loop that corporations do via the markets. Every stock purchase is a vote of confidence in a company to a degree, insofar as one buys a stock with the hope that it will increase in value. Unfortunately, the public doesn't have a fast feedback loop like this, and a lot of these decisions are made under the assumption that public either won't ever find out about it, or they'll be distracted by other issues.
