teach children about life after school

my idea is to teach children about all important things that come after school like how to get a job how much tax is and when you have to pay ect

Why does this idea matter?

iv left school in 2008 and i have no idea about tax and all the other things that i need to knowand i just feel that everyone should have an idea about how difficult it is and its not all plain sailing thank you for taking the time to read my idea
