This is a little simplistic.
Say a farmer can grow 20 bushels of wheat in a year. A farmer with a tractor can grow 200 bushels.
Does the guy who invented the tractor work as hard as the farmer? Probably not. But they (arguably) created much more wealth.
What about the banker who provided financing for the tractor? Let's assume it's a totally fair financial service, no need to stipulate anything predatory. The banker didn't work very much compared to the farmer at all, just wrote down some ledger entries. Yet without him, farmer is tractorless.
Any full view of the economy has to account for services and invention (and many more things, these are just illustrative examples.)
