Fascism, as established by Mussolini is very deeply related to plutarchy.
Fascist political philosophy is about racial purity, militarism, autarky, and suppression of dissent through political violence. In fact, one of their methods of enacting such worldview was by appropriating the wealth of rich people to advance their own purposes.

This is not plutarchy, the direction of control is going the other way.
"Corruption, but the other way around" doesn't exist.
