Today, lack of demand is a larger problem than increased output. The labor share of GDP has been decreasing since the 70s, and its starting to hit levels where people are having trouble affording as many goods. Although investing is a good use of funds, arguably redistribution (a type of demand-side stimulus) would be more helpful today.
