It's a little one sided, both in the Reuters piece, and in the media in general. Most journalist and politicians seems focused on the wealthy, but forget that the vast majority of people aren't poor because Mark Zuckerberg is rich. Sure, the wealthy needs to pay their taxes, just like everyone else, but it's not going to magically pull 2 billion people out of poverty.
absolutely right - wealth distribution isn't a zero-sum game
This universe and planet has finite resources. There is only so much iron/steel to build cars, rare earth metals to build electronics.. Fundamentally that's a zero sum game?
Sure in the recent short term, we've got lucky that population was small relative to planet size and we got significantly better each year at extracting resources. Even if we get lucky again and find a way to extract resources from space and energy from some amazing new tech. At some point that too levels off, especially as population keeps increasing exponentially, but energy capture/generation does not. Then we are back to zero sum game.
Historically most tribes/kings etc got rich at the expense of the workers/slaves they exploited. Wealth distribution has and long term mostly will be zero sum, or so it seems to me?
