The New York Times launches a series of investigative reports on corporate lobbying of state attorneys general. But you have to read fairly far down in the story to find the “nut graf” on why this is happening now. Radley Balko summed it up in a tweet: “As prosecutors get increasingly powerful, lobbyists will increasingly spend money to try to influence them.” And the article does note that:

A robust industry of lobbyists and lawyers has blossomed as attorneys general have joined to conduct multistate investigations and pushed into areas as diverse as securities fraud and Internet crimes.…

The increased focus on state attorneys general by corporate interests has a simple explanation: to guard against legal exposure, potentially in the billions of dollars, for corporations that become targets of the state investigations.

It can be traced back two decades, when more than 40 state attorneys general joined to challenge the tobacco industry, an inquiry that resulted in a historic $206 billion settlement.

Microsoft became the target of a similar multistate attack, accused of engaging in an anticompetitive scheme by bundling its Internet Explorer with the Windows operating system. Then came the pharmaceutical industry, accused of improperly marketing drugs, and, more recently, the financial services industry, in a case that resulted in a $25 billion settlementin 2012 with the nation’s five largest mortgage servicing companies.

The trend accelerated as attorneys general — particularly Democrats — began hiring outside law firms to conduct investigations and sue corporations on a contingency basis.

I wrote about this 30 years ago in the Wall Street Journal, citing Hayek’s assessment from 40 years before that:

Nobel laureate F.A. Hayek explained the process 40 years ago in his prophetic book The Road to Serfdom: “As the coercive power of the state will alone decide who is to have what, the only power worth having will be a share in the exercise of this directing power.”

As the size and power of government increase, we can expect more of society’s resources to be directed toward influencing government.

Those who work to increase the size, scope, and power of government need to recognize: This is the business you have chosen. If you want the federal government to tax (and borrow) and transfer — and reallocate through prosecution — $3.8 trillion a year, if you want it to supply Americans with housing and health care and school lunches and retirement security and local bike paths, then you have to accept that such programs come with incentive problems, politicization, corruption, and waste. And that special interests will find ways to influence such momentous decisions, no matter what lobbying restrictions and campaign finance regulations are passed.
