That's my point entirely. Capitalism does not breed competition, it breeds success for the private investor. Which in their case, they used government to kill competition and increase profit and personal outcomes, not increase competition and increase outcomes for all.
The idea that we can't blame Capitalism for its corruption is laughable. The greed motivation of Capitalism is WHY that corruption exists! Because they want personal success MORE than they want success for all, so they make a decision that benefits themselves/their investment at the cost of society.
The outcome of Capitalism without strong regulation in that era was a corruption of weak regulators, corruption of government, and a destruction of competition.
I guess you could argue "but what about Capitalism in absence of government entirely" but that sounds too much like the Communists and their "but but TRUE communism, without a state, would TOTALLY work, I SWEAR!"
