Quote from piezoe:
Well Piggy, it seems you didn't quite understand the NYTimes article nor do you understand Keynes. Spending public money on wasting assets for the sole purpose of creating a temporary boost in demand is not a very good idea.
Instead, what is being suggested, and what Keynes would approve of, is investing public dollars, even if those dollars have to be borrowed, in the private sector so as to create jobs building infrastructure (which includes for example things like high speed rail, developing energy alternatives, improving education, and constructing public facilities of all kinds.) This in turn will generate increased tax revenue and create demand in the private sector by putting folks to work on worthwhile projects, putting money in their pockets, and getting getting them off the unemployment/public assistance roles. The results of these projects can pay healthy dividends for years to come.
