if a drug were to be profitably sold to someone else for 20% of the price i’m paying for it, then wouldn’t i feel taken advantage of (more than i already am) when i’m denied access to that better price?
i’m not saying means tested benefits are (or aren’t) all bad: just that in most places we use them it’s to enable transactions that very directly could not be profitable. a person buying food with foodstamps isn’t themselves paying the producer a profitable sum: each stamp has a direct “cost” that gets socialized, so it’s reasonable to believe that somebody well-off shouldn’t be eligible for them. but when the transaction is profitable at both price X and price 5X, the case to be made for why everyone shouldn’t be permitted that price of X is just a lot harder to explain.
