You fix supply issues by increasing supply. Higher rates work against that.
Most, but not all, of our current inflation is energy driven, so Brandon needs to reverse his stance and actions that have restricted US based producers from running flat out. That solves probably a third of it. He can also reduce regulations in general to improve business investment to fix another third. The final third is related to the war, and I know you won't agree, but we need to get both sides to the negotiating table to solve that piece. The first two are easy, as he would have every Republican working across the aisle with him to achieve them. If we did that, the American people (other than me) would probably be okay with an indefinite war in Ukraine as tw-thirds of the problem would go away.
