You can only give what you have, sending your children to public schools isn't an abuse, the most important thing is for the children to learn how to read and write that's the essence of education. It has nothing to do with the school they attend. Parents should not be under any pressure to send their children to school they can't afford because they want to be good parents.
In western world, the public and private schools are likely the same, they have a good teachers and good structures for learning, is just Some Africa countries that they are still struggling to fit their educational system, when the see the state of the public schools you will be disappointed, sending your children to much environment looks like a punishment. That's the difference.
Good saying, trying to please others when you know you can't afford to meet up to expection yet you keep pushing all because one wants to please others and displease yourself. In life we know our financial strength is different from each other but the process of trying to do so is the problem we have as human. Some that where lucky enough to be boyant financially ends up sending there children to good schools why those that where not boyant should not try to compare themselves to the rich one just to feel among is the problem we should learn not to adapt to those nonsense
