WE GET LESS INTELLIGENT EVERY GENERATION
BECAUSE MODERN MEDICINE HAS MADE BEING STUPID LESS FATAL, AND STUPID PEOPLE HAVE MORE KIDS
bullshit has been discredited so many times. There is absolutely no correlation between income level and intelligence. Being poor has nothing to do with intelligence. Being poor just means one doesn't have what it takes to be able to attain quality education, higher or otherwise. Just because one is wealthy, doesn't mean he is any smart and vice versa. Being wealthy these days usually means you or someone you're descended from was unscrupulous and good at working the system. Most wealthy families today got wealthy on the backs of those they exploited for labour.
