Your desire for 0% inflation shows you are completely ignorant of basic economics. 0% long-term inflation would bring us into a deep depression.
Making all federal workers political puppets would be a disaster. A significant portion need to be protected so they can do their job without significant political pressure. Be careful what you wish for. It works both ways, for Democrats and Republicans. You want somebody like AOC or Bernie having complete control over who gets hired/fired from agencies like EPA, DOJ, FBI, Dept of Education, etc?
But anyway, Trump wants extremely low interest rates and was constantly telling Powell to bring them lower. You'd have MUCH higher inflation under Trump. If you look at month-to-month inflation data (not year over year), inflation was already skyrocketing before Biden even had a chance to do anything in 2021.
