Those things decrease GDP. Government spending on (as you pointed out) goods and services produced in America increase GDP. It worked in the 40's, it'll work now. It's simple math.
It's not simple math. If government spending was all that was required to boost the economy and create jobs, then we would never have to worry about any recession or economic crisis. After all, the government can just spend more money, right?
It's been proven time and time again, that you cannot spend you way into prosperty. Total GDP is not as accurate a measure as government spending as % of GDP. As government spending as % of GDP increases, economic growth shrinks.
