A larger scheme makes enough money to pay off those who might attempt to prosecute it. It's also generally more sophisticated, and has the means to hide misconduct. Look at those who are successfully prosecuted - mostly traders, small firms, 'rogue' employees. In one of the larger cases, SAC Capital, only a small number of SAC employees were convicted, despite it being 'common knowledge' that they engaged in insider trading, to the point that it was a central tenet to the firm's strategy, and traders brazenly collected insider information. And yet somehow, Steven A. Cohen has managed to escape punishment, as have the large majority of its traders.
