> It's important to remember, no company has stayed at the top of the S&P500 for very long. this has been true historically, but nothing makes it inherently so if you think in the context of a human's lifespan. 100 years ago, the world wasn't a continuously connected marked. If a company got "too large" for comfort, a government could intervene and force a split. This is no longer a viable action, as companies cater to literally the whole world at the same time, so splitting them in one jurisdiction would just end up making that particular market less attractive to companies... effectively harming the government economically. There is only so much you can deduct from our history considering that the base premises is so different nowadays, especially if you constrain it to the time we've got to experience this world. Microsoft and Apple at least have been around since before the 90th, so they're already 30yrs in... thats almost a full professional life of the average employee before they retire.
