Equilibrium of misery: add another lane to a highway, instead of people's commute being shorter as you'd expect, people adjust to live further away (they can get the same amount of house for less money, and they normalize back to the same commute, a quantity of time they know is viable).

Parkinson's law: the amount of things you have to do will expand to fill the available space.
