Taking a step back - who are you to say 1 billion was too much or too little for that mater - do you know everything that was involved. Too often articles in the media, to grab attention (their sole purpose) use these magic numbers - 1 million / 1billion ... so on so forth - again if you know the details and everything that was involved - sure, please comment. If not though, again, what exactly should this have cost? Corporations spend hundreds of millions on infrastructure all the time. But again if you know the details - and can state an appropriate amount - okay, that's a valid argument.
Another popular media grab is the salary of some high level government officials (hydro / ...) outrange typically follows when their salaries are states but the majority of the time they get paid less then what one would in the corporate world ... and why should that be the case ?
