Confuses correlation with causation, IMO.
Same thing with college-for-all. Okay, higher earnings are associated with college degrees. But maybe that isn't causative as a relationship. Maybe it's correlative instead.
Yes! Yes!
Correlation vs. causation was once explained to me in a wonderful way (paraphrasing from someone, but the details are all correct):
Sociologists have observed that increased murder rates in the New York metro area are correlated with increased sales of ice cream.
Question: Does this mean that eating ice cream makes you more violent??? Answer: No, it's a correlation without causation. Both increases are due to increased temperatures/heat waves. When it gets hot, some people want to eat a cool snack. Some people (not necessarily the ice cream eaters) also become more easily agitated when they feel overheated.
Okay, I love that one. I'll store it in my mind next to the ice cream conundrum.
