He noted that Wal-Mart had about the same levels of CapEx spending (~4%), yet it was also highly profitable by that point. Amazon isn't spending any more on CapEx than Wal-Mart was at the same stage of growth.
So Amazon isn't on some unique path in the business world by choosing to divert its profits to CapEx spending. Its level of CapEx spending is comparable to Wal-Mart at the same stage of growth. It simply has such low margins that it has no profits leftover after its CapEx spending.

Everything Amazon does, by contrast, is very clearly focused on one clear goal: becoming the retailer of record. It is able, either by institutional constitution or the nature of its market, to make investments in itself that will clearly add to its bottom line, either one or five or ten years from now.
A dream for many entrepreneurs is to start a fairly conservative line of business that buys freedom and a stable stream of revenue [consulting, online bookstore] and use the profits to fund a swing-for-the-fences idea. It's absolutely amazing that Amazon keeps that model going decades later.
