If anyone has any doubts about the answer, they need only look at the graph below, which shows that as the population of the world has increased exponentially, income per person has increased at a much greater exponential rate [source].

Clearly wealth is not a zero-sum game. This is contrary to the dire predictions of those who believe in Malthusian catastrophe and the theory of limits to growth popularised in modern times by the doomsayers at the Club of Rome.
A zero-sum game view of wealth is the primary economic frame of reference for the political left-wing. Socialists believe that the wealth I accumulate I take from others. Clearly their view is not supported by the facts as the second graph below (ibid) illustrates - as global wealth has continued to increase exponentially over the past few decades, the number of people below the global poverty measure (in absolute terms, not just proportionately) has dramatically decreased. Note that this decrease coincided with the period of greatest economic liberalisation and retrenchment of the state in more than a century.

One of the reasons David Seymour is in Parliament, and we have a pragmatic, centrist government rather than a diehard Socialist one, is that in the recent general election New Zealanders rejected the politics of envy. They voted for politicians that they thought would allow new wealth to be created so that they themselves can enjoy the benefits of that growth. In other words, they recognised that a rising tide raises everyone's boat.
UPDATE: If you want a real life example of an Ellsworth M. Toohey, there is none better than Paul Krugman, the economist and New York Times columnist, who is now calling for the greatest innovator in the publishing industry in the last 50 years, a company that has enabled writers such as me to bypass the traditional book publishing oligopoly, to be hobbled by the US Government.
