I don't think that this systemic view aligns with the campaign-finance-reform argument argument at all; the people who want money out of politics regard money itself as the root cause of the problem, but neglects to address the real underlying incentives that money - merely an abstraction of value - actually represents. If you take money out of the picture, those incentives will still exist, and still convey political advantage. Who dominates politics then, if not the wealthiest? The most well-connected? The most ruthless?
The real, underlying systemic problem is the centralized concentration of de jure power in a small set of political institutions. This will always be susceptible to concentrated influence, whether via money or otherwise.
Noone's claiming they have a perfect system, I'd be satisfied if we stopped sliding backwards.
What was wrong with the Citizen's United decision? What's wrong with high advertising spending?
Are you implying that voters are really so easily influenced by the mere volume as advertising that advertising alone is the overriding determinant of electoral success? If that's your point, isn't it actually an indictment of democracy itself?
Our modern trend toward increasing political centralization and removal of constraints on power is what's making corruption so lucrative and effective: if you build it, they will come.
Many of those who are most vigorously agitating for campaign finance reform want a strong and centralized federal government that isn't influenced by interests that compete with their own. But you can't have your cake and eat it too: if that's what you order, it's coming with a side of corruption (and a mixed metaphor fresh out of the blender).
No, your response doesn't address your goal at all. CFR doesn't do a darned thing to "reduce the effects of corruption". It seeks to decrease the possible vectors of corruption (both in quantity and magnitude), but it does absolutely nothing to address the effects of corruption.
What yummyfajitas and others have been arguing is precisely for a solution to the problem you cite, the effects of corruption. That is to make it so that it matters much less how a bureaucrat gets corrupted, by stripping him of power to the greatest extent possible, so that the potential for damage he can cause is minimized.
