The big difference there is that when a company is wasteful, they do it with their own money. When the state is wasteful, that's my money they are pissing away.
This difference is not that clear. Governments are bailing out failing banks and handing out beefy contracts; pension funds are owning sizeable proportions of the huge, slow, stupid companies, etc. All with my money.
Money is not my only issue. Bullshit jobs are also bothering me, as well as the fact that I'm forced to deal with such inefficient and stupid entities on a daily basis. Banking, shopping, whatever else - you can't hide from the large companies stupidity.
