All this info is widely available for free online, at the library, and sometimes in other free public resources like Citizens Advice Bureaus or Education Advice services. Education is all around us. No matter how good a school someone goes to, the onus is always on them to study and learn and make the most of what's available, not rely on others to shove knowledge into them. I had to leave formal schooling when I was 12 due to childhood abuse and homelessness and didn't return to formal schooling till I was 24 (and progressed on to PhD level). Everything practical I taught myself - how to balance my finances, maintain a home, write a CV and apply for jobs, etc. I know it's judgmental but I find it hard not to have a gut reaction when people say, "but I wasn't taught that in school!" Unless someone is illiterate (because that's something you really do need someone else to teach you/enable you to learn when a young child, and learning it as an adult is difficult and requires specific resources), has a serious learning disability, or lives a very disadvantaged life with have no access to the Internet. etc., that is a poor excuse.
Though I think I may be being too harsh, because perhaps part of the problem is that the education systems in some places don't instill kids with the idea of learning and finding out answers by themselves. The most essential skill any school, teacher or parent can teach is the desire and ability to learn, not any specific type knowledge or fact.
