IMO, a big problem is how to let people pick up stakes and find a place they want to call home. Assuming that the USA we know is replaced by a overhauled version, universal income and universal systems would be key to that.

Moving to a new place is expensive and fraught with complications - so having guarantees of a livable income, food, free basic shelter, healthcare, and so forth, would allow people to explore the land to find their better future.
