With the corporation, I only have illusion of control, zero transparency, and often contractual binding to an entity that only has incentive to take advantage of me.
Now, as far as government working properly: surely, it often doesn't work well. For one, governments are often too large (in citizen count) for individuals to participate effectively. This often leads to powerful interests taking over. But, perhaps this is because our governmental structures were invented way too long ago to be current.
The 'private citizen' part is interesting. I would prefer to have peer-to-peer relationships that are effective and strong enough. But, that's a ways off, isn't it?
