It's true what you said dude, when the leader of every country doesn't really care about his subjects the inflation average will increase quickly. But if the leader is good and has a lot of love for his people, he will definitely be able to keep the inflation rate low.
And it will keep the market price low which will not affect his constituents and will also raise the economy of the country he leads. But of course, if the leader is greedy and had no concerns for his country, the inflation rate will definitely increase in no time well many people will suffer in the end.
Inflation is largely the government's fault, I totally agree with that. But to say they can control it is not as easy as you think because our world is interconnected and all interdependent. For example, Nigeria is not a petroleum exporter, fuel prices increase or decrease. The Nigerian government does not have the right to decide, everything depends on the world situation. The covid epidemic is also a cause of inflation, and it is a surprise that no one can predict and prevent it in time, how can it be blamed entirely on the government when there are many objective causes? Moreover, when the government introduces policies to reduce inflation, do we comply, or will we resist because of doubt? And will continue to blame them. I'm not defending the government, but it's not entirely their fault, and we need to take some of the blame.
