True, but 30 years ago, I was paid $25 to cut a lawn with a push-mower. It would take about 2 hours. Now, a lawn service (not using illegal aliens) does the same job in about 15 minutes (because it has one of those quick ride-on mowers). They charge, wait for it, $25.
So there has been some economic "growth," there. The tricky part is how to measure it.
What took you 2 hours to do to earn $25
In 2 hours they can cut 8 lawns earning them $200
of course $ not adjusted for inflation
