Also, Apple isn't justifying its huge margins. Everyone who buys an Apple product is.
They're creating high tech, high-skilled jobs (product design, software development, hardware diagnosis and repair) at home, and outsourcing the low-tech low-skilled jobs to foreigners.
They once did create expensive gadgets no one could afford. Macs used to cost a lot more than PCs. Then Apple moved labor overseas, started pricing their products competitively, and now they have the highest market cap.
This is not on Apple..America lost the Automation race to Japan by being very strategically stupid
Apple is not to blame for that mistake
They're a big, successful corporation that likes to create great products and great customer experiences. Greed gets you Goldman Sachs or something. Greed doesn't inspire companies to improve customer service by keeping their support hotlines based in the US, it inspires them to outsource their hotlines to poor, nominally "English-speaking" countries overseas. The greedy PC and phone manufacturers didn't build expensive, high-end retail stores, they just shipped all their crap to big box stores, Amazon, and the carrier stores.
It turns out that Apple is profitable, because people like all those things Apple splurged on. So call it enlightened self-interest, but greed, in the sense of cutting corners to reduce costs, it is not. The next time you call Dell's customer service and end up talking to someone called "Mike" who has a suspiciously thick South Asian accent, or the next time you try to call Google's customer service before realizing it doesn't exist, you'll understand what mere greed leads people to do.
