But, around the world, political influence and anti-competitive practices (often sustained through politics) have been central to the increase in economic inequality. And tax systems in which a billionaire like Warren Buffett pays less tax (as a percentage of his income) than his secretary, or in which speculators, who helped to bring down the global economy, are taxed at lower rates than those who work for their income, have reinforced the trend.
但是，放眼全球，政治势力和反竞争行为（通常通过政治得以持续）已成为经济不平等性愈演愈烈的主因。在我们的税收体系中，像巴菲特这样的亿万富豪所支付的税收（以占收入百分比衡量）比他的秘书还少；把全球经济搞得一团糟的投机客所支付的税率也要低于勤劳致富者。这样的税制可谓助纣为虐。
