Problem is, we automatically tend towards hierarchical structures, that's our nature, we've been claiming we hate it for thousands of years, but we still do it.
Capitalism doesn't work in the same way that every other political of financial structure doesn't work, because no matter what rules we introduce to stop people acting like human beings, they just keep doing it.
The problem is that when breaking the rules works to the overall benefit of those in power, it tends to be ignored, even if that behaviour is ultimately self-destructive in the long term, which is a very human thing to do. What is needed is for the rules that already exist to actually be enforced.
The downside is, it's a knife-edge situation, because of the close links between industry and governance, something that hurts one hurts the other. That leaves the actual people whose money is fueling both groups as a kind of 'third party' from a political/industrial perspective.
