Finkle-McGraw began to develop an opinion that was to shape his political views in later years, namely, that while people were not genetically different, they were culturally as different as they could possibly be, and that some cultures were simply better than others. This was not a subjective value judgment, merely an observation that some cultures thrived and expanded while others failed. It was a view implicitly shared by nearly everyone but, in those days, never voiced.

Finkle-McGraw left the university without a diploma and went back to the farm, which he managed for a few years while his parents were preoccupied with his mother's breast cancer. After her death, he moved to Minneapolis and took a job with a company founded by one of his former professors, making scanning tunneling microscopes, which at that time were newish devices capable of seeing and manipulating individual atoms. The field was an obscure one then, the clients tended to be large research institutions, and practical applications seemed far away. But it was perfect for a man who wanted to study nanotechnology, and McGraw began doing so, working late at night on his own time. Given his diligence, his self-confidence, his intelligence ("adaptable, relentless, but not really brilliant"), and the basic grasp of business he'd picked up on the farm, it was inevitable that he would become one of the few hundred pioneers of nanotechnological revolution; that his own company, which he founded five years after he moved to Minneapolis, would survive long enough to be absorbed into Apthorp; and that he would navigate Apthorp's political and economic currents well enough to develop a decent equity position.

He still owned the family farm in northwestern Iowa, along with a few hundred thousand acres of adjoining land, which he was turning back into a tall-grass prairie, complete with herds of bison and real Indians who had discovered that riding around on horses hunting wild game was a better deal than pissing yourself in gutters in Minneapolis or Seattle. But for the most part he stayed on New Chusan, which was for all practical purposes his ducal estate.
