My parents are charging me rent. Is this fair?

Ever since I turned 18 my parents have been taking 150$ from me a month. I’m now 22. I know that doesn’t sound like a lot, but I’m only making around 400$ a month from my job. That’s almost 1/3 of all my wages. They’re well off and do not even need the money. I asked them if they’re saving it for me for the future and they laughed in my face and said I sounded entitled and that I should “contribute” to the house. I understand that that is fair, but I could contribute in other ways, especially since I only make 400$ a month, and all of that money goes to my car gas and car insurance. I don’t have any money to save because it all goes to them and my car. What do you think I should do and what should I ask them? Thanks for any help.

Btw-
I understand this is fair and it’s their rules because they own the house, I was just trying to get everyone’s opinions to see if this is unusual or not
