>What is the difference between economics and power relations?
In an ideal world, economics would study power relations as they relate to money -- that's what the old economists (19th century and so) called "political economy".
In the present world, economics are a shallow ideology around the "free market", with naive abstractions and axioms. Usually these are mostly peddled by the media and "popularizer" economists at the masses, but what actual academic economists sell is not that much better.
