ANYWAY, my problem with deregulating government, and allowing people to make their own choices (in this regard) is a bad idea because businesses will align together to control the masses. Say in a free market, it is assumed that businesses and consumers have complete knowledge of a product, something we don't even have now with a government that supports consumers (or so is claimed). However, if one company, through any means, becomes more powerful than other companies, it can not only consume others, it is now closer to creating a monopoly, as it is unlikely that other businesses will join to bring down the first.
Now if this company engages in illegal/shady/unethical practices, it is possible that someone could find out and inform everyone, and they will stop buying from that company. However, this company could be powerful enough, they could influence news outlets, media sources, etc to not inform the public or even denounce and slander the person/people trying to expose these practices. Word will get out - maybe through old fashioned means such as pamphlets, etc - but people will be so bombarded by messages from other sources, that they will just forget. Even if enough people find out, and say a law suit is created, the business will not only be able to hire the best lawyers, they will be able to, and most likely try to, buy out the opposing legal team. Even if prosecuting lawyers decide not to take the bribe, the business's allies in the media will be able denounce and defame them, and removing public support.
And what about businesses that rely heavily on government contracts, such as the arms manufacturers? The government is unlikely to remove contracts with these companies if they indulge in unethical practices, otherwise the US government would have no PMC's in Iraq, but that's a different matter. One could say that the people will vote them out during the election, but within the 3-5 years between elections, what is the likeliness of people remembering some bad business practices from years ago. And who's to say that the other party will stop dealing with the company in question? Democrats/Republicans, Liberal/Labour (in Australia), act pretty much the same.
Therefore, my belief is that IF we are going to live in an almost free-market economy (it probably won't change for a while, no matter what I want), then the government should have enough regulation to stop corporations, and the people themselves should become more active to stop inter-business collusion, and collusion between governments and businesses.
