This is an interesting question. It is true that the schools can ask donations and they can start financial campaign as soon as your child gets accepted to your school. Whether or not you will donate, or how much you will donate entirely depends on you. The idea that because you does not give any donation, the school will discriminate is wrong. If any school discriminate a child because of that, please let me know. Parents and students also have the right to ask questions. I do not how much they ask or how they ask, I know that sometimes, parents of students works for this financial campaign together for their children's schools. Of course, you will decide when you want to donate, not the school.
