Why would it be okay to let advertisers know you have an interest in cars? Seeing personally targeted ads affects your autonomy. I don't want to be influenced

Why would it be okay to let advertisers know you have an interest in cars? Seeing personally targeted ads affects your autonomy. I don't want to be influenced by ads on every website that are targeted by my socioeconomic status, such as the potential ability to afford a holiday outing or purchase a car inferred through interest in holidays and cars. Being able to differentiate on interests such as 'holidays' and 'cars' as compared to 'fast food' enables advertisers to sell the same product at different prices to different socioeconomic groups. This is bad for society.
