That means if we hold constant the profit earnings, if you bought the whole company at its current valuation ($4tr), it would take you 37 years to break even.
Is this reasonable? Depends on sector and growth potential. To me, this is a "fair" valuation and not overly inflated based solely on existing earnings.
Or 16 years at 5% inflation.
We use it as a snapshot in time to check our sanity and to allow us to compare apples to oranges.
That said, you could have made the same statement about AAPL or MSFT 20-30 years ago, and you would have been dead wrong.
