That goes a long way toward explaining (add a bit of ideology to the mix) why the current Greek government has gone to the brink of default before agreeing to restrain public-sector pensions, as its European Union partners demand. It also helps explain why both Greece and Argentina have sizeable governments (public spending accounts for 46% and 39% of GDP, respectively) but puny public investment and outdated infrastructure.
或者，试想公共部门工会否决改变成员福利的情况。这非常有助于解释（在解释中加入了一丝意识形态意味）为何希腊中央政府要到违约边缘才同意按欧盟伙伴国要求抑制公共部门退休金。这也有助于解释为何希腊和阿根廷政府规模都十分庞大（公共支出分别占GDP的46%和39%），但公共投资却微不足道，基础设施也陈旧不堪。
