For example, interventions aimed at changing individual behavior are far less challenging to prevailing power structures than those that demand extensive social investment or revitalization of the entire system. Thus, governments interested in closing the health gap – such as the British Labour government in 1997-2010 – usually end up pursuing such relatively painless “downstream” interventions.
比如，旨在改变个体行为的干预对现有权力结构的挑战远比要求大面积社会投资或更新整个体系的干预药要小。因此，有意缩小健康差距的政府——比如1997—2010年的英国工党政府——通常会选择痛苦相对较少的“下游”干预。
