We don't work as hard as we used to, we don't produce like we used to.

Our society has gone from one of growth to one of decay.

You can't do as much when you want to work a few hours a day a few days a week with seasons of time off.

You can't do as much when the supply of energy is falling over time.

You can't do as much when regulations grow and grow, making building anything less and less worthwhile and less and less possible.
