The age window when kids gain exposure and mastery of the internet keeps dropping and today there are 10-12 years olds that can perfectly understand the concept of bitcoin and are not hooked on the current system either. If they can do that and are interested in putting some of the money they make from a lemonade stand or from selling an application into bitcoin, they should be encouraged to (with the supervision of adults if possible).
Those at more of a disadvantage are the elderly who have gotten too used to the current system to change their mindset, but we have people changing that narrative as well.
