So what next? The best first step is to free up labor markets world wide. Specifically, we need policies that take aim at the unbearable political forces that seek to tighten the regulatory noose on voluntary labor markets.
Unfortunately, the dominant attitude of macroeconomists is to assume that nothing that takes place within the labor market (of which Krugman never speaks) is large enough to influence the large macro trends to which they attribute today’s high employment rates.
The blunt truth is exactly the opposite. The calcification of labor markets is the primary impediment to economic recovery. The direct effects of government regulation of labor can matter far more than the indirect effects of macroeconomic policy, whether Keynesian or austerity-based. Neither austerity nor lavish public expenditures will improve the overall situation, which is why the massive increase in American public debt has not nudged unemployment rates down. The only workable solution has to stress job creation, not by misdirected subsidies, but by dismantling the government obstacles to market exchange.
