Hey Yassin!
Enjoyed reading your idea.
My comments are only going to be relevant to the United States but I think there are at least two ways to try to influence curriculum outside of lobbying.
Start your own school. A few states in the US have recently adopted or broadened voucher programs which which allow some level of state funding for private schools. You could start a school and try to fund it via voucher students- the Drexel Fund lists the states with the most generous voucher schools as Florida, Wisconsin, Indiana, Ohio, Louisiana, and Tennessee . Starting a charter school (a publicly funded school that has to comply with many but not all of the same rules as traditional public schools) is also an option and lots of US states have provisions to start these.
Provide a boxed curriculum! You (or someone) could provide pre-made lesson plans, reading packets, Youtube videos, a website for teachers with draft tests and assignments. Then try marketing them to teachers, districts, private schools, homeschooling parents, and so on.
US education is super-decentralized- there’s no national curriculum which makes it hard to generalize. In my experience, individual teachers can’t set the curriculum but have choices within it. For example, a US literature teacher might have to cover certain themes or historical periods but could choose specific readings.
The Ayn Rand Institute offers free books to promote Objectivism, and some US schools teach her novels.
Philosophy courses in US high schools are pretty rare.
Maybe developing relevant lesson plans for statistics or psychology classes and placing them on teacherspayteachers.com would be a good way to gauge interest?
