To go from middle-income to high-income status, countries have to redeploy resources to high-productivity, knowledge- and skill-intensive sectors. That is a transition that Greece and Argentina, with their financial instability, poor infrastructure, and weak education systems, have never made.
而坏政治学带来了坏经济学。要想从中等收入步入高收入，各国必须将资源重新配置给搞生产率的知识和技能密集型部门。希腊和阿根廷从未实现这一转型——它们的金融不够稳定，基础设施破败不堪，教育系统也十分孱弱。
