wealth isn't a zero sum game. Not to mention that it's a false dichotomy to claim that the wealth increase could only have came from taking it from someone else.

The pie may be growing, but when the rich take proportionally more from the pie every time it grows, then to the poor, it might as well be zero sum. To use the other analogy: it's a rising tide, but only the rich have boats.

From a purely theoretical standpoint, you're correct.

In reality, it definitely feels like zero sum when the government moves to eliminate social programs so they can give a tax break to the rich.
