If we actually lived in a "just" system, when people are executed for murdering a single individual, which many people have been, we would certainly execute people for things like, say, losing billions of dollars in pensions for the elderly with greedy mathematical trickery. In a just world, hundreds would have been executed for the financial crimes of 2008. "Justice" only exists when there's threat of punishment. It isn't enough to have the moral high ground; you have to have the might and the will to enforce the moral ground on others. Humanity will always live under systems of "oppression", but it's what that oppression looks like that matters, because there'll always be someone who takes advantage of a system's goodwill, and that must be punished swiftly and brutally, to deter anyone from abusing the system's goodwill.
