    I am Queens Blvd.
    Utility, to me, would be dollars or "happiness points." And sometimes you can use dollars to "buy happiness points."

    Like, for instance, I have the choice to go to the amusement park or to the movies. The amusement park costs $20 while the movies cost $10. If I go to the amusement park, I go with a group of friends that I really enjoy. Also, I enjoy the amusement park more. The amusement park trip is worth 30 happiness points.

    When I go to the movies, I go with one friend that is meh. Also, the movie will probably just be OK. The movies are worth 15 happiness points.

    Let's make one dollar and a happiness point equal in terms of utility.

    I lose 10 utility units to go to the movies but gain 15 for a net of 5.
    I lose 20 utility units to go to the amusement park but gain 30 for a net of 10.
    I obviously choose to go to the amusement park every time.

    Obviously, this question was simplified for mathematics sake. Most people value money more than I do making my dollar to "happiness point" ratio pretty low. But yeah, there.
    That's how winners play; we convince the other guy he's making all the right moves.

    Is there a dollar~happiness ratio invariance? Is 10 dollars today worth .4 happiness points tomorrow?

    This is the trouble I've always had with these descriptions. I kinda get where they're going, but with the exchange rates of happiness~dollars changing by the hour, I just don't see how it works.
