Even if advertisers make more money from the rich (citation needed), the poor are still disproportionately negatively effected. I would argue that it's less ethical to persuade someone with $100 to their name to spend $10 on something they don't need, than to persuade someone with $1,000,000 to spend $500 on something they don't need.
To bolster this argument, look at the things that are most advertised to the poor: alcohol, gambling, fast food, and predatory loans (including predatory auto financing).
The wealthy, meanwhile, are more likely to be targeted with ads for lifestyle goods: health foods, travel, gym memberships.
