|The economic allocation problem.|
I think the greatest trick economists ever pulled was that economics is about our well-being. The so-called fundamental theorems of welfare economics are based on a peculiar defintion of welfare (see here for an in-depth view). And people such as Diane Coyle point out that measures like GDP don't capture our well-being, innovation or quality of life. That came up in Chris Dillow's latest post on the subject where I found the following quote:
The biggest difference between New Yorkers and primitive tribes, he says, isn’t the “mere 400-fold difference” in their incomes, but rather the 100 million-fold difference in the number of products available to them.
Not only is "primitive" in the eye of the beholder, but so is the linear difference between 400 and 10⁸. If money represents information, then the proper measure would be the logarithms
log 10⁸ ~ 20
so that the difference is less eye-popping.
Economics doesn't strongly depend on innovation (measured crudely with the number of products). Each new product adds only about 1/n to log n, meaning each new product adds a smaller and smaller amount to the total amount of information that needs to be gathered in order to compute the allocation.
Economics is not and should not be about us as humans . That might even get in the way of understanding economics (or may just be unnecessary). Economics is about the functioning of a particular allocation algorithm (see also here). Full stop. Politics and philosophy is about us as humans and our well-being as a society.

Also, try to avoid the use of dollar signs as they interfere with my setup of mathjax. I left it set up that way because I think this is funny for an economics blog. You can use € or £ instead.
