Der Premierminister von Manitoba verspricht, die Provinzsteuer auf Lebensmittel aus Lebensmittelgeschäften abzuschaffen

This doesn’t stop prices from rising. It just delays the pain. Any relief is temporary, because prices keep climbing and consumers end up right back where they started. The difference is the government has now permanently lost that tax revenue. So consumers still face high (or higher) prices, the deficit worsens, and grocery oligopolies pocket higher profits. So this is effectively a subsidy to those oligopolies.
