While I agree that there is some hyperbole in the article, I think it's worth pointing out that this is a fundamental (if not the fundamental) business concept: Buy/make a thing for price x and sell it for price x + profit. $200K/mo is a little much for this kind of low-hanging-fruit but easy/easier money DOES exist. Your next startup doesn't have to be a blockchain AI distributed whatever whatever that's going to change the world. If you can afford to use distribution centers (there are some that come ready made and will drop ship and do stuff for you), and can find a niche/gap in the markets and fill that niche/gap until it's no longer there. That said, this is low hanging fruit (basically arbitrage), and difficult in practice, as logistics (storing, shipping, inventory, etc) is hard. If you can do it easily, odds that others can too, and more will enter the market, and reduce your profit margin. I also don't need millions to feel like a success at such a startup -- If I were to make a setup like this (and I know people who have, though they focused on specific niches), and get away with 50K a year or 100K a year, I'd be very happy (assuming the logistics were little to no work after initial setup costs).
