Soup is NOT a meal
Soup is at most an appetizer and should never be served as a main dish. It's basically impossible to get full on soup, i don't care how much filling there is.
Soup can be good, especially if you're sick or have a sore throat but other than that eating soup as your main meal shouldn't be as normalized as it is. If i go to someone's place for a meal and they made soup, I would go home hungry. As grateful as I am for the meal it should never be considered enough to fill anybody up.
