"They amass billions by siphoning it away from the majority of people in the market, and in return give us nothing of social value."
How are they "siphoning" anything away from a majority of people?
How are they giving nothing in social value? The money these people make they spend on other business ventures, familial needs, education, healthcare, charity, do you have any evidence at all that this money is going into a black hole of sorts?
I thought not.
So would the guys a few milliseconds behind - that isn't a relevant point. And that's not even what the parent was referring to about "social value". They mean about giving a sense of "worth" to publicly traded companies, which compels them to make sound business decisions. And the "siphoning" refers to a lack of a "level playing field", which is the reason we have laws against monopolies, price-fixing, etc...
