We temporarily had like 20 phone services, and we ended up back with (barely) 3.
I think there are 2 "solutions" to try: - breaking up a company once it becomes too big; separating the various business it operates, so that they cannot have unfair advantage of consolidation and competitors have a better chance (it's easy to "win" when you can subsidize one branch losses with another high margins...) - preventing them from becoming so big in the first place by forbidding them to buy any other business. If they have to grow organically it would take lots more time, require more ressource from the main business and take years to be competitive. I never understood why we let some companies swallow another just because it has the money. Companies with too much cash on hand are pointing at an economic inefficiency and it just means they should be taxe more because they are stealing too much ressources from the world.
Anyway, we end up in those situations because we assume a lot of things that are just plain wrong, in the first place the notion that the pie just gets bigger. It's fundamentally false because ressource are limited (natural ressources, numbers of humans, total available time, etc). When you make runners compete, you give all of them a single, similar lane; you don't just let a single runner push everyone out of a single lane... But the second case is exactly how our economy works...

More seriously, each of those companies could be split without too much trouble and no loss of shareholder value. Microsoft in particular seems to be made up of components that work against each other.
You can also obviously just buy a PC and run whatever you want, but the entire point is the barrier to entry. If it's easy, more people do it, and that's good. If they have to contend with a convoluted mess, people give up, and you lose whatever they might have created.
What would be the economic and geopolitical consequences of the US breaking up the only US companies that are globally competitive? Chinese giants will outcompete the smaller less competitive remnants after these kind of corporate breakups.
This may or may not be true, but size is not necessarily a predictor of victory, especially in warfare.
History is rife with smaller belligerents defeating larger ones through innovation/force multiplication/asymmetrical warfare.
I think it's fair to say that an oligopoly stifles innovation; you can see it in how expensive and slow companies like Lockheed, Boeing, or BAE are when it comes to providing matériel needed by actual warfighters.
I don't think this is an either-or scenario – you need both – but saying that we can only be globally competitive on the backs of megacorporations is incorrect.
American big tech companies aren't competitive in anything. They're entrenched monopolies. Google, Apple, Microsoft, Meta, and Amazon products are all shit, but users don't really have any other choice. If we break them up, it will create market opportunity for actual innovation in the US.
The question is whether we actually have the talent and expertise to innovate once you remove all of the current artificial barriers (big tech monopolies, walled gardens, etc).
I think we do. At least more than China, where most of their big tech companies seem to be built on stolen and cloned tech.
If their products are all shit, how are they able to maintain their monopolies? Why hasn't a competitor started up that offered a better product?
It's a little of both to be honest. I disagree that their products are shit (in fact some of their products I think are really damn good), and I don't see how short of coercion with government or a private army or something that you could maintain a monopoly with products that suck.
But I genuinely think I might be missing something here. Maybe a better question is, how are they able to maintain their monopolies with shit products? Huge barriers to entry combined with quick acquisition of competitors? That's mostly how Rockefeller did it in the 19th century, but that's not a good parallel either because he didn't have a shit product.
