You don't fight anything this way. If, given that the interest rate is 2% annually, all users were entitled to this reward, it'd nullify its purpose. If everyone became slightly richer, with constant national gross product, then nobody would actually gain anything. Prices would just rise, that's all.

Inflation and deflation are complex problems, that require complex solutions. Commonly political problems. That's why you shouldn't try searching for a technical solution.
