Roy Cohn and the Lionel Corporation

Roy Cohn left the government in 1955 never to return. He decided to go after the next best thing, acquiring the wealth necessary to keep fucking with people. By 1953, it was the largest toy manufacturer on the planet. And of course, he proved to be absolutely terrible at the job of managing a toy company. So basically under several years of Roy Cohn's management, Lionel collapses leading to Roy's ouster and paving the way for the company to be bought by Neil Young.
