In my country  found a job is very difficul

Most people  have high education  but didn't have a good job.then theye force to do a job like carry bags in supermarket  or taxi driver and so on

It depends on the type of graduation. Scientific ones will normally allow you to get a job quite quickly. However, if you study Communication or Psychology, for example, you should prepare yourself to a carrer into a supermarket or a baker's.
