(To be clear, Berkshire could buy any of the bottom 476 companies in the index, not all of them. Also it’s probably closer to 400, because Berkshire has to keep some cash around to pay insurance claims and so on.)
Thanks - that is an important distinction in a perhaps intentionally misleading title
Warren Buffett is the legitimacy canary for any claims related to "bringing manufacturing/heavy industry/etc back to America." If there were any kind of non-bullshit plan to support the deployment of blocks of $10B to $100B on anything other than chips and data centers- which for damn sure we need- he would be first in line. But no. So he gets to sit around, eat his burger and coke, and collect $15B in interest on that cash.
