I was rewatching the movie Brewster's Millions (1985) the other day and there's this one scene that caught my attention: when the title character goes to check out his 30 millions at the bank the person in charge tells him he will get the "special interest rate" of 24% a year.
Is this a realistic value for that time? Nowadays the interest rate is less than 1%. Were the eighties banks that generous? Or is this a normal value for very wealthy accounts, even today?
