Interesting observation from lefty journalist Ron Fournier:
The American public has lost trust in virtually every social institution—schools, churches, businesses, charities, police, courts, and the media—because those entities have been slow to adapt to sweeping economic, demographic, and technological changes.
I don't know about all of them, but for schools and businesses, I think a substantial part of the problem is too much badly drafted and enforced legislation and regulation. Example: much of the recent upset in higher education is the direct result of the recent extension of Title IX to topics it was never intended to cover.
Refutable hypothesis: cut back Big Government--especially federal government--and trust will recover.
