I totally agree with your statement that education is not a scam and can never be a scam. I believe we only feel that education is a scam based on the where we find ourselves,  a country where we have a lot of graduates without a job. I still don't think this is a enough reason to see education as a scam.
Education has its benefits,  firstly education gets to prepare you for the society. It's helps you understand morals and how to live with others in the society. I will not say that education guarantees that you will be rich, but it's a bedrock to being successful in life. Education gives you a sense of reasoning and it also helps you in everything you endeavor to do in life, because it helps you to make right choices,  be it in career part or in business.
