There's no question that when a specific person receives government cash (specifically, cash that has been described as Keynesian "stimulus") that such person is now richer than before.
The problem is the idea of "stimulus". The Keynesians (being dunderheads) see "the economy" as a merry-go-round stuck in neutral without "stimulus". That's preposterous. There's no basis for such an assumption in fact, logic or history (which is why Keynesians get absolutely hysterical and call you names when you challenge them).
As we can all see from recent events, the forced wealth transfers do nothing to restart the stalled merry-go-round (which is stalled in the first place DUE TO KEYNESIAN POLICIES).
