I'm currently at uni, only reason I'm doing uni is to basically get a pay rise. With a piece of paper (uni or tafe) you can generally have more of a say in what pay rate you'll get.
I don't need uni to get a job, it's just expected that either people have some kinda of qualification these days in order for them to stand out over other applicants and be of more use to the organisation.
But in saying that, no point having a degree if you will never use it.
Gotta have my say
