i want recomendations about a certain type of series 

i want series where the main hero or main heros are rich people girl preferably but can be a whole group friends or family who are rich and arrogant ...especially to their maids 

series that point out social class differences and poor people being arrogant to the ones who serve them

i hope i will read some recomendations 

Yong Pal 
The Winter the Wind blows
Innocent Man
Its okay to be not okay - she is rich, he is not per say poor, just normal income
Itaewon Class
You who came from the stars - not per say poor but he is an alien

the type with maid story is more fit with;
The Heirs - he is rich, she is the daughter of the maid
Secret Boutique - revenge drama, she is poor but worked her way up to fight a rich family
Hotel King - she is rich and arrogant in the beginning, he is her employee.

Sadly I cant think of more

The Penthouse: War in Life
