Given how unreliable pensions are in modern times, I bet there'll be fewer people to scoff at my suggestion: whack it into stocks!
Even in the old days, when pensions could be relied upon, they still weren't as good as stocks, but the problem is scaremongering. People with little or no actual knowledge just cry "crash" and their job is done.
But I wouldn't be surprised if less than one in one thousand people in this country know the very real and established fact that historically, on a real long-term basis i.e. not one year, not three years or even five years, but decades, the stock market has far outperformed all other forms of investment...including property!
I'm sure there will be many people who will argue the toss over this, but the figures are there in several easy-to-find sources, for anybody to see. I myself found this out in a high brow historical study of stocks over the last century here.
I shalln't do your work for you Doubting Thomas; I just suggest you don't pipe up without first looking into it. I can't recall the numbers, but I do remember the chart, and exactly how the line representing stock market profit grew steadily, geometrically away from all other lines over the years and decades of the twentieth century. Now what you might validly argue, is that such a trend will not continue...but that's just conjecture, whereas I'm supplying historical information for the last one hundred years!
