If you can trust the processes of government, then that is a good thing. Good trust in government is based on processes that provide for accountability, checks and balances, equal protection, and punishment of official corruption.
Trusting the virtues of government leaders is a bad thing. It leads one to cede rights and powers to government that are easily abused.
...My idea of a high-trust society differs from that of many elites. Elitist journalists think that a high-trust society is one where we trust the mainstream media. Elitist politicians and activists think that a high-trust society is one where we trust legislators, regulators, and experts to exercise broad authority. In contrast, I believe that a high-trust society is one in which processes ensure that elites are subject to checks and accountability. It is particularly important for legislators, regulators, and experts to have their authority limited and their accountability assured.
