This is something the US Army at least has recently started trying to tackle. If you fail to meet the education or fitness requirements there's a 90 day course to help you reach those goals: https://www.armytimes.com/news/your-army/2022/10/11/the-armys-pre-boot-camp-boot-camp-is-likely-to-expand/ https://www.armytimes.com/news/your-army/2022/10/11/the-army... I'm neither American nor involved with any military - but this came up in a podcast I was listening to recently, as a potential solution to recruitment problems that the US Army was having recently. It's a fairly good one, IMO, and certainly a more reasonable one than hoping people will decide on their own to "lose weight, be taught to read and write"
