Can someone help me answer this question?

PACs have been called “collection agencies” for interest groups. They were created to evade laws that forbid corporation and labor unions from giving money “directly” to federal candidates. These laws still exist. Aren’t the laws now a farce? Why does congress permit the law to be trampled by allowing the existence of PACs? In 1982, Time magazine concluded that PACs threaten “to undermine America’s system of representative democracy.” Is this statement accurate given the information provided in the text?
