According to the Edelman Trust Barometer, more people trust businesses than trust the government or media.
Business is more credible than government or media in 13 of the 18 countries surveyed in 2007. The survey also found that more respondents in 16 of 18 countries felt that companies have more of a positive impact on society than a negative impact.
In the United States, 53% of respondents report trusting business, which marks an all-time high for the survey. This is a recovery from a low of 44% in 2002, which came in the wake of the Enron and WorldCom debacles. In the three largest economies of Western Europe, France, Germany, and the United Kingdom, trust in business stands at 34%, which is higher than trust in media and government at 25% and 22% respectively. The 2007 survey marks the lowest levels ever of trust in government across these three European countries.
Pretty dismal numbers all around really, but I think the reason people trust businesses most is that they are more accountable than government or media. If you don't serve your customers then you don't get to stay around. Businesses have to show results. Governments just have to show rhetoric.
