Normally, 9 to 5 jobs pay minimun wage, and are steady/common. Being a member of congress has high requirements to get to the level of being able to pass laws, bills, to veto the President's laws, and many more responisbilities. Having a 9 to 5 job means being a civilian with basic rights and knowledge. Working your way up to being a member of congress is highly prized, uncommon, and rarely attainable.
Hope this helps :) -Laura
