College Graduates Earn More Money
"College graduates earn more money!"
True fact. Wrong conclusion.
The conclusion everyone makes: go to college, get rich.
The actual situation: rich kids go to college. Smart kids go to college. Rich and smart people make more money. Maybe college helps. Maybe it doesn't. We don't actually know.
You can't just observe that successful people went to college and conclude that college makes people successful. That's like observing that basketball players are tall and concluding that basketball makes you tall.
