I am about to finish up the book pictured above. Peter Schweizer does a good analysis of how politicians are not just some innocent group of people corrupted by money but actually prey upon business by threatening to use their power on them unless some cash is thrown their way. Schweizer also touches on the people connected to politicians who help write legislation that then “Cash In” after a law is passed with big lobbying firms because the legislation is so complex. Their services can go for up to $1,000 an hour at some places. Here is a passage from the book, pages 129-130 describing studies covering political contributions.
