The point of the article is that investment in Amazon is growing because Amazon has a business model built on stable infrastructure and expansion modeled as a large conglomerate of essentially separate business groups which distributes risk, and is thus better able to weather negative environments (see e.g. the stock's behavior during recent economic crises). It's being used as a hedge against volatility... in the short term. Because that's how markets operate. If you believed that you could make more money in the same amount of time elsewhere you would put your money there instead.

anyone with a spare $100

Being impoverished doesn't just mean that you're unlikely to have a spare $100 at any given time, it means that any negative life event is that much more likely to wipe out any savings you may have been able to accumulate, including an investment in securities.

You can say the same thing about public sanitation.

>Education isn't a right. It is a choice.

That's a poorly thought out platitude. Plenty of rights are also choices such as the right to vote, to remain silent, to bear arms, to a trial by jury.

No, it's your duty. Society suffers, in general, when people are not educated. We really should insist on requiring more of people.

I can tell with certainty that my kids do not have all that much choice when it comes to education. By the time they will be old enough to get that choice, their education will be mostly done thing.
