is it a stereotype of lazy girls just going for 40 year old men for there money

Yes, the idea that "lazy girls" pursue older men primarily for their financial resources is a stereotype. Stereotypes simplify and generalize behaviors and motivations of individuals based on gender, age, or other characteristics. In reality, relationships are complex and based on a multitude of factors, including personal values, emotional connections, mutual interests, and compatibility. Not all women seek older partners for financial reasons, just as not all older men are solely interested in younger partners for superficial reasons. It's important to approach each individual and relationship without preconceived notions and to recognize the diversity of people's motivations and experiences.
