Re Scot Lehigh’s Nov. 16 op-ed “Enough supply-side silliness”: Republicans remain attached to supply-side solutions partly because they believe that low taxes and interest rates are sufficient to spur recovery, and partly out of an abhorrence for deficits and distrust of activist government. Democrats believe that low taxes and interest rates are necessary, but not sufficient. That’s why they focus on deficit spending — to put money in the pockets of consumers, or the demand side.
Republicans believe that making more capital available for investment will induce businesses to expand, increasing employment and sparking recovery. However, business people generally want to see recovery on the horizon before they expand.
