You can find the same jobs without GED as with it. In today's market GED (and even AA) is useless.
Having a GED or degree does open up possibilities.
No for most people in reality it doesn't.
I dropped out of highschool to go start earning money after an unfortunate series of events caused me to have to repeat my junior year of high school even though I had more credits at the end of my sophomore year than most juniors had at the end of the same school year.
I went back and got an Adult ED diploma which is supposedly = to a HS diploma and supposedly more valuable than a GED because a GED only requires you to take a test and does not require you to sit in a classroom to earn credit hours which an adult ED HS diploma , unfortunately when you have a substitute for an actual high school diploma most employers screw you on pay and throw you to the curb if you explain why the rate is unsatisfactory, legitimate gripe or not and this is not repeating what someone who doesn't really know says about how it works...this is my life experience.
Most of the time the guy doing the hiring has a degree in something and I think there is some sort of complex in the mix causing him to think that if he hires someone that on paper barely has a HS education and that person outshines him it will make him look bad so even if you do get hired, doing an awesome job could get you canned.
I helped tutor people in night school because I always had all my classwork and homework for the night done within 30 minutes of the class starting (classes were 2 a night 2 hours and some change a piece) and in the whole time I attended until I got my diploma which I did after work hours I only ever answered one question in any assignment or test incorrectly.
Does it matter...no, the only jobs I can secure with that piece of paper that can actually afford a decent living are the same extremely physical labor jobs which I was doing before I got the diploma and a person can't do those jobs forever, also if you look at the numbers in the trades I do most of the people doing those jobs die within one year of retirement at an average age from 59-62 years old.
I worked with a guy that had to keep working at 58 years old with an artificial heart and two replaced knees one of which had to be replaced twice just to be able to keep his home and a hot plate in front of him at the table, when I had that job I had to pay almost 7000 a year out of pocket for medical insurance and could only go to specific places to use it vs the guy who has full medical coverage and who's job is not dangerous at all (you know, because the people who build the schools that people earn their degrees at and the buildings that all the office types work in don't need medical more than the guy who's most dangerous part of his job is a possible paper cut or a sore on his butt from sitting all day).
Ultimately if you don't go to a university and get a degree (it doesn't matter if you earn it or not, as long as you have the piece of paper saying you did) you will have a very small chance of getting into something that can furnish you a lifestyle worth mentioning. I have friends that are as dumb as dog chit and partied all through college, drunk E'd up and coked out of their minds every night and bought their grades and now they have great paying jobs in which they do very little, and then I have friends that earned everything they have by working hard and most of what they are entitled to they will never see.
Since I assume that you got your GED in an effort to help you establish something in the way of a career I would suggest that if you can afford to further your education to a higher level than do it, otherwise hope you get hired by someone who can see your potential and views you as an asset rather than a threat that can put out numbers for him in the temporary until he replaces you with another drone.
In my experience going back to get that piece of paper saying I finished high school was useless and a waste of my time.
