I'm not in a position to do the research at the moment, but I'd suggest that African-Americans have very clearly and for a very long time suffered state control for financial exploitation, and they are not the only ones, but simply the largest and most visibly egregiously maltreated minority.
Look at property values in areas with high levels of police violence. It's a chicken omelette in a way, but your definition of fascism does seem to fit the situation for this and other US subpopulations.
That's exactly the primary purpose of the police. The police serves capital and the state (which also serves capital) in order to exploit and control the people.
It's my own preferred definition (Eco's definition), the essay itself is very short, highly recommend it. No mention of state or corporation.
You are thinking of fascist corporatism [1], indeed a much more pointed critique of the USA's political practice than traditional fascism. But also, "traditional fascism" goes only back as far as Fascist Italy, which practiced corporatism, so perhaps all fascism is corporatist.

If anyone is interested in American history: Before we had our modern police departments, our earliest systems of law enforcement were actually slave patrols and organizations called Indian Constables. These institutions are rooted in controlling the behaviors of minorities. If you know your history, you know that slavery and colonization never really ended. The 13th amendment, world-leading prison labor system, and border camps are part of this living legacy.
