My dad was a member of a fraternity in college.
His dad was a farmer.
And my dad got an engineering degree.
Not sure the fraternity membership did anything for him, during or after. He wasn’t a party animal. And he got an excellent education many, many decades ago.
And had a very successful career afterwards.
Guess it depends on the Greek.
Probably, or the generation. The level of “education” at college is nothing close to what it was when your father went.
