If one is uneducated, it means that he/she are illiterate, it will be very difficult to find a job with pay that can satisfy all the needs that people have. The job that one can get will be something down the lines of being a cleaning person because you don't need to know how to read or write to do that. There are many basic health and life lessons that are gained from getting an education which means that an uneducated person will not know any of these essential school taught things.
He/she will be more likely to be criminals in the future given the fact that they do not have anything to do, except if they have their own jobs.
Being uneducated has it's advantages and disadvantages. Ever heard the saying "Ignorance is Bliss" The less you know the happier you'll be and the less worries you have however being uneducated also makes it harder for you to find jobs.
