This is short, but it demonstrates something that's been missing from tv for a while, which is the simple interview with children that recognises they are children but still takes them seriously as humans.
EDIT: Somehow I missed the main link, which goes to a BFI page here: https://player.bfi.org.uk/free/film/watch-children-and-politics-1964-online
There are some amazing old (1960s, 1970s) British tv interviews with children carried out by Harold Williamson. He asks children a question and then just lets them answer. There's no attempt to laugh at the children, and there's no attempt to say "zomg look at what this cute kid is saying".
It's showing its age - "what would you do if your husbands went on strike? How would you run a household?" (asked of two girls) isn't acceptable.
