The only way I see any sense of "market forces" being allowed to work normally is to completely excise the ability of businesses to be involved in the political process. No corporate donors, direct or indirect. And something like max out of pocket $1000 per person per candidate per year. Money in politics is causing all kinds of distortions that aren't good for markets, or consumers, or taxpayers. Good for basically subsidizing certain for-profit industries and their share holders.
