That is a real benefit on the big mac side, but in my current value scale it can't compete with the hours of delight, the self-improvement, the aesthetic pleasure, the deep insights in human hearts, etc. I am rewarded with when reading, say, Pride and Prejudice.

That's not inherent to the book, it's the value you put on the book. To my 8 year old brother, you can be sure the Big Mac will provide much more pleasure

The value system you are pitting against money is completely subjective and therefore somewhat useless as a points system.
