The Economics of Convenience

From classical economics:

The return on land is rent.

The return on labor is wages.

The return on capital is interest.

The return on management is profit.

When I took economics in college, there was some debate about what the return on technology really was. (I’ll throw in my two cents by suggesting that it’s markets.) But it’s a different consideration in personal economics. If we’re already well-off, the return on technologies that make things “quick and easy” is probably just additional leisure time.

But what’s the return on “slow and difficult”?
