The fact is that in after 2007 the poor man was doubly penalized. On the one hand his nominal income took a plunge and insult was added to injury when his job was taken away! The chart compares nominal income growth (NGDP) during the two cycles. Is it hard to see why consumer spending (and all the other components of GDP) and employment crashed?
The chart shows a big drop in Nominal GDP during the Great Recession.
Looking at that big drop, Marcus says it is easy to see "why consumer spending (and all the other components of GDP) ... crashed".
Marcus says, in other words, that the reason all the components of GDP crashed is that GDP crashed.
Sir, that explains nothing.
