I suggest substituting, "accomplished" as a descriptive term for people who have succeeded and who, as a result, have justly received the wages of success. There is nothing inherently "privileged" about someone who has earned a great deal of money. Indeed, there is nothing "privileged" about inheriting a great deal of money, that person is simply the beneficiary of someone else's accomplishment. The ability to bequeath wealth is an incentive to create wealth and therefore enriches everyone in a just society.
If we don't like to substitute "accomplished" we can say "virtuous." but substitute something we should.
Or “deserving”.
I agree with you, to even engage them in the argument is to accept their premise which means you’ve lost the argument.
Perhaps the proper answer would be “f**k you”
