This. Unfortunately, young people are told that if they go to college/university they'll find jobs that will allow them to live a good life. Not true. Hard work and dedication increases your chances of finding such a job...and college/university is just one (and most common) of many paths that help you get there.
There are no guarantees in life. But as posted above, statistical looks at the information are pretty clear. You reduce the odds of being unemployed by about a factor of 3. And you increase your probable income drastically. A University education is not a guarantee of success. It does however stack the odds in your favour. I am taking a post grad distance learning course in probability and statistics. One of my recent assignments was to find ways to express probabilities in a way to make them clear to the average person.
Roughly, if we accept the 2 charts already quoted... If we had 4 people playing poker, and 2 had university educations and 2 did not, it would be like the two without university education had to keep any face card they were dealt but they did not count for winning any combinations.
They might still win, but the odds are not in their favour.
By the way that is an example, and I did not calculate the odds in this case. But I would be in the ball park.
