In most US states, a student can legally drop out of school at the age of 16. While some students may find it tempting to drop out then to avoid two more years of school, the lifetime of poverty and suffering that often follows it are often far worse than pushing through another twoo years and graduating. I'm 27 now, and I am already old enough to see the consequences of people's choices from when they were 16. Among other things, I know people with a lot of college debt and no job to show for it because they picked an easy major, I know kids who died from doing drugs before they turned 20, and for dropping out of high school, most of these people tend to be stuck in a cycle of poverty in which they never get to enjoy even the modest standard of living that they had under their parents.
Here's how the cycle of poverty starts. I'm starting a business now, and one of the things i look for in an empployee is whether or not they are responsible. A high school or college degree tends to show that the person applying for the job thinks enough about their future that they are willing to do things they may not like in the present. Since work in high school is extremely easy compared to real life, dropping out means that someone is unable or unwilling to handle relatively easy work, and may not be able to follow directions. So, I would either not hire them, or pay them very little at first. Also, the people I knew who dropped out tend to be people who choose to never learn to follow directions, they tend to bounce from one low-paying job to the next, and since they didn't learn math in high school, they often get ripped off by pawn shops and payday loans, thus making their financial situation worse. This financial poverty often breeds despair.
The bottom line is, every one of your teachers wants better for you. That's why they show up to school every day. Please heed them and takee advantage of the free education they are offering, because free education doesn't get offered again in life.
