Economics is too broad. For example Land and Real Estate is zero-sum, as is strictly Debt/Financial/Monetary exchange.

Some things, as with blue skies research, really do create more wealth as in overall some technological advancements make making some things cheaper, or available.

Creating debt to print capital now for making X cheaper to produce is generally good as that zero-sum is offset by the wealth/wellness created by that capital in the future (a company producing cheaper components for example).

Meta exists in a zero-sum market, as advertisers fight for the same limited resource: attention (an individual can view as much advertisement in 24H).
