Nothing has been proven whatsoever. This article just said a whole bunch of nothing really. I have faith that the CPP returns will be good enough and that this enhanced CPP will be a good thing for today's young people. I won't benefit from it as I'm already 46 and will probably be retired within 10 years, but I am glad that the younger people will get better CPP. And don't bother with the "people can save better for their own retirement". Baloney. Most save NOTHING when left to their own devices.
