Fortunately the notion of "country club" prisons for white collar criminals is largely a myth. Some prisons are less bad than others though.
Especially in the United States, your penal system seems to be much harsher than in the UK. Over here our white collar criminals would probably be sent to what is called a category C prison, which is basically an open prison for non violent offenders. That's if they don't buy their way out of the charges using slick legal teams.
