It actually says that the more educated you are, the better chance you have at finding a job. That someone with a 4-year liberal arts degree has a better chance at finding a job than someone with just a HS degree. That's what the chart says.
Not sure how you can devise any other conclusion from that link.
OMG, it does matter. You can see it in the unemployment rates yourself; the unemployment rate for a HS diploma is almost twice the unemployment rate for a 4 year degree. Also, the higher your education, the higher your wage.
So after all this you still cannot manage to get a HS degree. Talk about leading a horse to water.
