I know I've given you this answer several times, but the best way to solve this problem is to get inflation down.
Yes, the most vulnerable members of society are particularly affected by inflation. With the fact that inflation is quite broad now, more than two-thirds of the CPI basket is rising over 3%. Even if you are a very careful shopper, you cannot avoid higher prices, and there is a role for governments to protect the most vulnerable members of society.
Monetary policy is a broad macro tool. We can't target specific individuals. Those are decisions for governments and Parliament.
