In economics, regulatory capture occurs when a state regulatory agency created to act in the public interest instead advances the commercial or special interests that dominate the industry or sector it is charged with regulating. Regulatory capture is a form of government failure, as it can act as an encouragement for large firms to produce negative externalities. The agencies are called "captured agencies".
So the companies that are regulated and have to bear huge overheads in taxation and paperwork go after the ones who dont have the burden ie they divide and conquer.
