He built a successful dry goods store and an 80-acre farm, showcasing his entrepreneurial acumen. Kinney transitioned into public service, serving in the Illinois General Assembly and as Lieutenant Governor. Despite his political career, he faced financial challenges due to poor investments during the Panic of 1837, which nearly bankrupted the state. Kinney's influence extended to recruiting key political figures, such as Lyman Trumbull, to the Illinois Board of Public Works.

His advocacy for mercantile activities and establishment of a prominent dry goods store juxtapose with his ardent support for slavery, revealing a complex alignment of personal profit and moral conviction. Despite his financial mismanagement during the Panic of 1837, Kinney's role in shaping Illinois' political landscape through his influence on Lyman Trumbull suggests a calculated approach to regional power dynamics.
