"The labor force has decreased by millions. Those millions are spending less. Provide them with the opportunity to work and their consumption will increase."
********
You seem to be countering your own argument. You're saying work generates income leading to consumption, but taxes on that work decrease income which decreases one's ability to consume.
You completely missed my point. Probably my crappy writing. My simple point is that, contrary to current economic fads, consumption does not drive the economy. Production does.
Claiming to spur economic growth with a paltry 2% drop in payroll taxes is economic sophistry.
P.S.: I will miss the 2% payroll tax break. That said, the economic facts still stand.
