There is a name for it: revolving door. This how legally permitted corruption reproduces itself in the USA. There is a prosecutorial discretion. Except for prosecuting mafias (RICO is useful), it is very hard to prove collective culpability in any large company--that's why many executives are off the hook. What appears to be unethical to the public (revolving door) is legally permitted. Basically, it is a collusion between DOJ/SEC/IRS employees, and ex-DOJ/SEC/IRS employees
