Here's the fallacy in Carrick's argument.  While the CPI or other inflation indices that he relies upon may be accurate, they do not reflect the actual rate of inflation that low income seniors face in the limited basket of goods that they routinely purchase - food being a prime example.

In the supermarkets where I live, no price ever increases by just 1-2%.  At minimum an increase will be at least 5%, sometimes 10% or more.

Meanwhile, senior couples with combined household income in the low six figures are still receiving OAS with a very, very slow, generous clawback as their income increases from there.
