Rule number 1. Get an education, any education...make an attempt to better yourself. Learn all you can while you can, you will be surprised how far it will take you. When you get an education, even at work, you are making an attempt to improve yourself and things like that are noticed by the bosses and it might open up opportunities. Learning takes work and you would be surprised how many people are too lazy to continue learning, then they wonder why they no longer earn more and move up. If you quit learning, you will stagnate and then move backwards because there are people coming up that are hungry and you will find yourself obsolete and unemployed and wondering what happened.
Rule Number 3 Don't get pregnant. This rule applies to both girls and guys. For girls, getting pregnant early unless they are lucky and have a great family structure in place, will be trapped in a cycle of poverty. Sure they get benefits from the government, but the money they get is just enough to keep them trapped in a continuous cycle. "Why work when I get money from Uncle Sugar." they sell their dreams and soul for an EBT card. Once the baby arrives, it will be difficult to continue getting an education to improve themselves and they will be trapped where they are or even slide into a worse situation than they have now. I remembered this girl in high school, she wanted to get into NASA, and become an astronaut. She was brilliant and we could see her making it. But she got pregnant and had to drop out in the 11th grade. A few years later I was working at Domino's Pizza after graduating high school and a year of college then ran out of money. I was delivering pizza as I was making ready to join the Army for the G.I. bill so I can go back to school. Well I was delivering a pizza to a dilapidated trailer and this same girl came to the door. I immediately recognized her and asked her how it was going. She told me that she had her baby and was pregnant again. I then asked her " where is your husband?" She commented that he was probably at the bar getting drunk. I continued to make small talk for a few minuted then I left. I had an epiphany as I was leaving. Where she is now is the highpoint of her existence. It is a slide to grinding poverty from here and I was a bit bummed. This rules also works with guys, if you get a girl pregnant, you also are responsible and you will have a 18 year commitment and if you and the girl break up, expect to have child support and possible garnishments to deal with. Rather than going to school to get a higher education, you have to enter the work force at a lower paying job to make ends meet and your dreams are on hold perhaps indefinitely.
If you follow these rules and apply a modicum of common sense, you should be able to avoid the lower parts of the economic ladder.
