Your problem here is the same as your problem with climate change...your teenie weenie brain thinks micro when the problem or issued discussed is macro.
The article confuses the US economy with individual incomes. The article mentions income as the only source of individual wealth. Just last week the Federal Reserve published its quarterly z-1 report. The report showed the net worth of Americans at an all time high.
It obvious that you completely fail to understand this point that has been made repeatedly...we have an oversupply of labor and a shortage of demand for labor. This is B-A-D for income growth. This is not necessarily B-A-D for the overall economy. More people are working which increases the T-O-T-A-L level of income in the entire economy...this means the economy will continue to G-R-O-W as that increase in total wages is spent. Employment growth is not strong enough to drive up wages...this is B-A-D for at the household level and also means that economic growth will be subdued.
The world really is a lot more complex than the X vs O, tic-tac-toe level of comprehension you possess.
