No matter government take over power supply or SP services continue managing power supply or inviting 5 other power vendors to create "competition"... each and every one of them would like to make the $1b profit...
Think of it this way; put yourself into this big pair of shoes... If you were in the position to manage the power company, don't you think you want to earn significantly more money from the work you do and earn more and more each year (aka yearly increment and variable bonus)? Or would you be willing to work for free + forgo the increment and variable bonuses for the benefit of fellow citizens? Who can be so selfless? Not the people in SP services, not the people in government, not you and definitely not me.
