Two points to consider in your situation you describe are:
(1) Most parents worry terribly about their children and their successes in life. It is only totally natural for parents to seek the best hopes for their children, and unfortunately, the so called "best hopes" can be nothing short of the way the parents "did it". This is a loving, but wrong viewpoint. I must confess guilt myself in this area. A parent would love seeing their child successful, which to them means fully careered, and no immediate future worries. A parent thinks (incorrectly) that a child learned from them while growing up, and is plotting the same course the parent laid out for them: Get an education, get a career job, get a home of your own, get a bank account, get friends that are just like the ones I had, and get married and have me some grandchildren. A parent of my generation thinks that is success for their child. Success is in the eyes of the individual. To you, success would be avoidance of a "bad situation: job as you mention. Success to your parent would be your "having" a job. So please don't be too hard on them as I am willing to bet their interest is in your best future.
(2). Times have changed---drastically. Many parents don't realize this, and are still living in the 1990's. Let's face it many older folk will not pay too much attention to the web when it comes to sites like this one, or going to alternative news sites. These folks are main stream media, straight laced and they "know" from experience just how things should "be done". There is a mystical generation gap in every set of parents/children/grandchildren. Just wait, if your parents don't think your walking their walk, wait until they get the grandkids, and it just gets worse. So don't suffer because your parents aren't buying in. They don't understand, but I bet they really really care a lot about you!!!!
