In his Nobel Prize Lecture economist Gary S. Becker remarks:

Different constraints are decisive for different situations, but the most fundamental constraint is limited time. Economic and medical
progress have greatly increased length of life, but not the physical flow of time itself, which always restricts everyone to twenty-four hours per day. So while goods and services have expanded enormously in rich countries, the total time available to consume has not.

The more stuff we consume, the less time we've got to enjoy it.
