I heard this on the radio recently and was amazed.
When flappers were dancing in their speakeasys the human population was only 2 billion. When Kennedy was president, the Earth held 3 billion. Today, we are 7 billion.
That’s right – flappers only had a dating pool of 2 million! And now there’s so many people that people can’t even get jobs, because there is simply no need for so many people.
