And as I've pointed out at times previous when that claim's been made: there are companies whose annual revenues exceed many nations.
WalMart has an annual income of $482 billion.[1]
That's more than the annual GDP of Poland, as measured by the World Bank, the 25th largest economy in the world, and of Belgium, the Philippines, Thailand, Norway, Iran, Austria, the United Arab Emirates, Egypt, South Africa, Hong Kong, Malaysia, ... and 153 other countries (163 total) in the world.[2]
I think the reason that can work is that (the vast bulk of) Walmart is entirely dedicated to executing on a single, very well defined (and easy to measure) task - their supply chain.
Unfortunately, few problems in the world are like that, and that's why large companies (and governments) fail to address them effectively.
