Re: 40c an hour?
"It's just nonsense to value people's time at under 40 cents an hour."
It certainly is. I would suggest that most "facebooking" happens outside of work, or at least a significant portion of it, so it then becomes recreation, which is consumption, so if anything that would take from GDP, not add to it.
The only way you can value a persons time in monetary terms is if they are producing, hence adding to GDP, or being non-productive when they could be producing "work". For example, I enjoying repairing things so if I spend a couple of hours fixing something I could replace for £5, have a wasted money by spending 2x£20/hr fixing it? Of course not. I'd have been vegged out in front of the telly, or going for a walk, or interacting with family or friends. At no point would I be earning wages outside of work time, but my quality of life is improved if I do something I enjoy. You cannot measure that in cash.
The sort of people who measure all of their time, 24x7, in terms of their hourly pay rate when at work are the people who live on shitty take outs and ready meals because that's cheaper than spending an hour cooking a nice meal, right?
