Yeah, the Kansas-Nebraska Act, that horrible piece of Yankee corporatist legislation(?)
No, I would not say corporatist as I am fairly sure that that philosophy was not all too present in Antebellum America. It is not inaccurate, however, to state that the Kansas-Nebraska Act was supported by agricultural interests and that Senator Stephen Douglas of Illinois introduced the bill in part because of land speculation.
I'm sorry if my post comes across as a little bit agressive, and you're obviously correct about what was the motivation of some of those backing the bill (not a total U.S. History illiterate over here), but it strikes me as odd that
that would be what you find problematic about the Kansas-Nebraska Act. Feel free to correct me if I misunderstood you.
