But did they really increase spending
I suggest you spend some time studying Personal Consumption Spending data in the NIPA data series.
Yes Americans really have increased there spending to the deteriment of personal savings and investment.
I can't believe your source only had access to data up to 1992 when they calculated the locus of real wages per hour.
So, where's the rest of the data, have you asked your source?
Remember, you're trying to convince us that this is a good deal for taxpayers.
