Sam Altman and Andrew Yang talk UBI

However, it's possible to see how Amazon being broken into at least one online retailer, a web services company, and a logistics provider and how that may increase competition in each of those markets.

Further, even in your social example, people used Instagram before Facebook bought them and likely still would if divested, and Snap, Tik Tok and more are going strong as independents.

It's ridiculous my tax rate is over 30% while wealthy people has it at 15%, and Amazon has it at 0%. That's the real problem! Yang wants to give people #1kBro so they can shut up about the real issue here is tax fairness.

First, you assume that having multiple competitors is pointless if one product is the clear winner. Proponents of breaking up tech giants would argue that Twitter and Facebook are not actually very good products right now, and the reason they're popular is largely due to network effects and anticompetitive behavior, not innovation. They would argue that even if breaking up Twitter just resulted in 2nd-best Twitter, the existence of competition would force the original Twitter to innovate at a faster pace than it's moving right now.

Second, you assume that there would be a clear "best" product. In truly competitive fields, it's often difficult to point to one product and say, "that's the best, and everyone else is settling for a worse product."

Take iPhone and Android. Why does anyone use the 2nd best phone operating system? Why don't we have one OS? Because there isn't a clear 2nd best operating system. The products are good for different things, and fit different niches and use-cases. It seems obvious to me that the smartphone market is broad enough that other niches could be served better by more targeted alternatives to the two major OSes, if those alternatives were allowed to mature to the point where they became competitive.

Finally, you misunderstand what the proposals about breaking up tech companies often entail. Most commonly when people talk about breaking up big-tech, I find they're talking about Warren. Warren's proposals are (roughly speaking) about separating product offerings and platforms. Her plan isn't to take Apple and force them to split up and create a second iOS. Her plan is to split Apple so that the company controlling the iOS App Store isn't the same company selling software on that store.

It's not about blindly making a second Apple, it's about trying to remove conflicts of interest from platform maintainers.

I'm not going to say whether or not I think that plan is good. I do think it's pretty unlikely to happen even if Warren is elected. But regardless, it's a very different, much narrower plan with very different goals and implications than what you're describing.
