I'm British and l can categorically say that Britain for one has not become a hellhole 3rd world country .
Have you been here recently? Where do you get this information from ?
Back to the topic. I'm ruddy positive that the two witness rule doesn't and shouldn't apply to this situation. Who on earth is going to sexually assault or rape a child in front of someone else who isn't a fellow paedophile.
DNA and other evidence obviously helps but very often children need to work up the courage to tell someone about abuse. It maybe that an abused child waits until they are an adult to report an abuser . By then any physical evidence will be gone .
