"But $1 billion added to the domestic economy through tax cuts to promote personal consumption (like the payroll tax holiday) adds 15,100 jobs."
that never actually happens, though, because most of the money ends up in savings accounts or paid down as debt (and i'd expect the share going to debt is so high at this point that tax cuts are basically banker handouts). to the extent that jobs are created in retail or whatever, it's short term and cyclical....
it's cursory to the argument, which i concur with.
