Im not an economist. In my uneducated mind its says either: A: Americans havent improved productivity in that timeframe. (Ludicrous notion). B: the value of the productivity gains in that timeframe have been going to money printing cantillionaires through an extractive monetary system. You'd need to run that past a macro guru. In either case, stack sats cause this system aint working for you

Actually, random thought, is this a reflection of the scale of malinvestment in a financialised system?
