Many new people in the State of San Andreas experience a lack of knowledge and experience on how to start up a job and earn money to sustain themselves and their needs.
Currently, jobs such as, Taxi, Post Delivery, Gardener, and few others available careers in the job centre are not always easy to understand or get started with. As a result, they are neglected and forgotten, leading to a large amount of people not doing anything to benefit themselves and society, leading to chaos, people harassing each other, increase in crime, and no motivation to strive for a higher purpose.
How could this negative impact be reversed? Very easily. If the higher-ups of the State of San Andreas would contribute towards a more thorough and flashy introduction into the standard jobs, it would increase the diversity in the jobs people have an experience with, keeping them in the city for a longer duration and increasing the daily population very easily.
