I've traveled to many cities across the U.S. I even lived there for almost 2 years. In casual conversation Americans don't trust the government at all and hate paying any taxes (generalization, of course). But OTOH they don't seem to resist big business at all.
For example, my neighbors were outraged at a proposed 0.5% increase in local sales tax, and that conversation lasted weeks. But when someone had their car alternator replaced unnecessarily, or myself I had a completely fraud quote saying I needed a whole new roof (in fact there was nothing wrong at all), their response was "Well, what are you going to do?" as if there was nothing they could do, and they just accepted that. To me (Canadian) that seems entirely backward.
It may seem hard to trust government, but nor can I trust big businesses like Bre-X, Enron, MCI/WorldCom, NS Power (Emera), GM, Siemens Energy and Automation (it's personal!), any big U.S. bank or insurance company, Bell, Rogers, Apple or Nortel, just off the top of my head.
I get a vote for my MP, MLA, councilor, etc. If I join a party I (usually) get a vote for the party leader and a chance to introduce and vote for policy resolutions. I get the same vote as any other, regardless of how much money I have. But in a corporation, the number of votes I get as a shareholder is proportional to my investment, so those who invest more money get more say; further, customers seem to have none. The notion that you can choose to do business with a different company is typically laughable. If I don't like NS Power, what other power utility do I use? If I don't like Rogers cellular, I could switch to Bell - for all the good that would do (oligopoly based on huge barriers to entry).
I trust businesses to be perhaps more predictable than government, but I NEVER think businesses are working in my best interests.
