In children period, deceive us must study hard, but when we grow up

Design a fable cartoon:

In children period, many expert, member, officer, education administrative institution, and the school, and the society, often say and encourage to children: If you study very hard now and can be persistence, you will be successful in future, in future you can have a very good and stable job, have very high income, have more money etc.
But when they will grow up, the reality is different as above of these. Only less people can be successful. Employment opportunities will be less. Many person's income are less, and many person's income will be reduced. But living costs and tax will be increased. Commodity price will be increased more, no money to buy many things. Many people's life will be hard more.
