Not sure if this is what I'd actually go with, but the first three things that come to mind:

1) Enact congressional term limits and vastly increase the size of both the House and the Senate

2) Make large-scale white-collar crime punishable by death, and also extend some additional form of punishment to the families of the perpetrators

3) Establish a framework for randomized in-home general welfare checks for all citizens (limited to basic psychological testing and screening for most obvious signs of physical abuse - funding for this and related programs would come out of the war department's budget)
