The only one of these that has anything directly to do with capitalism is tool manufacturers. Fortunately, that's a great example! Let's dig in a little.
Go to Home Depot. Lots of tool brands to choose from, right? Ridgid, Milwaukee, Ryobi, Makita, maybe a couple of Hiltis over in the contractor section. Amazing variety thanks to capitalism, right?
Wrong. The first three brands I listed all belong to the same company, TTI. The only significant difference among them is in build quality, and it's minor; other than that, all that changes is the injection molds for the shell, and the price - which varies out of all proportion to the quality of the product.
That's not a true choice. That's an illusion of choice, deliberately promulgated by a near monopoly in order to gain access to as many market segments as possible, and exploit each to the maximal possible extent - by pretending to compete with itself, TTI makes a lot more money than if it didn't, because that means it can sell three kinds of differently shaped boxes of 18650 cells, and in the modern consumer/prosumer power tool business, that's where all the margin is.
That's great for TTI! For everyone else, not so much, because only the Milwaukee line doesn't actively suck, and even then you're better off spending more for Makita, precisely because that's not a zombie brand, and is still competing.
So, TTI's a great example of capitalism, sure. Is it a good thing? One of the major complaints about Soviet communism, after all, was precisely the lack of consumer choice that it imposed. If that's really the crux of the problem, then why isn't it a problem when capitalism produces the same outcome? Is it only a failure when the Reds do it, but an example of freedom and apple pie when the same exact thing happens under capitalism? Why?
