The problem is not lobbying, that's a symptom. The problem is deep and multi-fold. On the one hand you have a very broken and ineffectual news media which focuses on trivialities and scandal and otherwise ignores all else. A media which has perverted the process of gaining elected office by making it unpalateable for most folks, leaving it only to career politicians and glory hounds. On the other hand you have a bloated and excessively powerful government. The increase in tax revenues, laws, and regulations in the last several generations has concentrated a great deal of power and control of money in DC and in state capitols. This excessive power invites corruption, when every business depends on the activity of congress then every business will do its best to influence congress.

The only long term solution to the problem is to improve journalism (which is happening slowly) to encourage a better class of office seekers combined with a reduction in the importance of government in business and daily lives, to make it less worthwhile and less necessary for businesses to influence government.
