So you're arguing that we don't need to hold GWB to account. Fair enough, there were mitigating circumstances. But then in what sense is the government accountable for anything?
Corporations and government are both held to account through the courts, I suppose. But the government will often change the rules so it isn't accountable (eg, wiretapping scandals), so that is a weaker form of accountability than a corporation faces. Is there an actual meaty argument to the idea that governments are more accountable than corporations? Because I'm drawing blanks on the times when a government was held to account for anything in a manner that wouldn't also apply to corporate actions.
Given that record, I think there is a better argument for putting him in charge of the US healthcare system than putting the people in overseeing the healthcare system in charge of Amazon. Bezoscare written by Bezos would likely be much more effective than Obamacare written by the US Congress.
And I still don't see the argument that the US government is somehow more accountable than he is.
That said, the US does have term limits to at least blunt the damage when the balance of power and even impeachment don't suffice.
