In the US, I would make history part of the standardized testing done by states and make it part of SAT/ACT tests. Too often it’s a neglected subject even though there are many valuable lessons from it.

Same with government class. People need to understand how government works, how to get involved, how to vote. Make high school students attend a court trial one week as part of their class. Make them vote in a mock election using the actual voting equipment used in elections.
