"...not that these boomers are going to be destitute when they retire. It’s more that they will not be able to afford the luxuries to which they’ve grown accustomed..."

well, tough darts. 

Instead of engaging in an "epic rant of frustration," I'd advise Mr. Rosentreter to engage more "everyday Canadians," who not only might value his advice, but actually show up for the second meeting. 

I also suspect that many of the super-affluent boomers may also face one other unpleasant reality of life as they approach or begin retirement: that multi-million dollar house they have a sizeable mortgage on may ...just...not...be worth what they think it is when they decide to downsize to an $800,000, 1500 sq. ft. one-floor rancher.  It won't take a major real estate bubble-pop to lower the present home's value.  Just timing.  In another example of herd mentality, they will decide to sell the mini-mansion just about the same time millions of others do.  Can you say, "Glut on the market?"
