It was a big deal in my town when the city allowed the local Walmart to start selling grocery items. The concern was that the long-running local grocers wouldn't be able to compete.
I'm under the impression that the majority of commenters on HN are pro-Capitalist, and while these Capitalism-critical articles occasionally make it to the second or third pages of HN, nobody really wants to talk about the deletrious effects that Capitalism wreaks on the working poor. It's not just Walmart, the article also mentions McDonald's, as a provider of "cheap", "bad food", which is making people sick.
I know that a lot of people in tech are really, actually trying to make the world a better place; but... if we can't start discussing and unpacking some of our base assumptions about how the world actually works, we're just adding more fuel to the fire, feeding the beast, enriching the rich while impoverishing the poor.
I'm not starting a war... nor do I think that the other "ism", Socialism, however it might have been, or be, implemented, is the "one true economic theory" that will save the world from poverty. The world is not Black and White, no matter how many "Cops" episodes might portray otherwise.
I do think that we should question the status quo, and meaningfully consider, and attempt, alternatives to it.
My personal experience with pro-Capitalist folk is that they tend to view the world as a zero-sum-game, whereas I see it as a non-zero-sum-game. If there are any pro-Capitalists here who also see the world as a non-zero-sum-game, I would love to hear about your perspective. Hell, I'd love to hear your zero-sum-game perspectives as well, although I don't think they'll change my mind. But who knows?
People already in power have no incentive to change the rules of the game (as far as I can see). But people just now gaining power (e.g., people in tech), do have an opportunity to change some of those rules, and could very well "undo" some of the damage that has been done by the incumbents.
Again, just my 2c.
