Eli5: why do people use the term Middle class instead of Working class?

Question

Isn’t middle simply confusing?

Are we not working folks and wealthy-ruling folks that generate wealth via assets?

Edit: thank you all who’ve helped me gain a better understand of the concept from many different angles

Answer 1

What is confusing about it? There’s a lower class (mostly made up of blue collar low-wage workers), middle class (good blue collar jobs, white collar professionals, small business owners) and upper class (family wealth, business executives, highly paid professionals etc.)
