之所以有这么好的印象，想必是因为以往的行程，几乎都是被精心安排好的。我和同事们在顶级医院观摩学习，在名牌大学的学术报告厅交 流，或是在跨国公司可以俯瞰城市天际线的会议室里开会。交谈对象，是美国社会最顶层的一部分人，都是自信、优雅、高效的精英。就算 偶尔有闲暇自驾，也是一头扎进壮丽的国家公园，在山川湖海间感叹造物的神奇。对于真实的美国社会，我仿佛始终隔着一层无尘玻璃，看 得见，却摸不着。 以下文章来源于张琨随笔 ，作者张琨 张琨随笔 . 勤于思考，勇于实践，乐于分享 本文来自微信公众号： 张琨随笔 ，作者：张琨，题图来自：视觉中国 这应该是我第几十次踏上美国的土地了吧，单是过去这一年，便已是第四次。过往的记忆，美国在我心中是非常好的印象，"灯塔国"的代名 词，全球创新的引擎，医疗技术的麦加，精英荟萃的殿堂。 今天，我稍微击碎了这层滤镜，回到酒店，带着一身"叶子"味道，写下这篇小感。 今早，我心血来潮，在酒店附近的便利店里买了一张TAP公交卡，决定用最本土、最接地气的方式——公共交通和徒步，去探索这座"天使 之城"的心脏：洛杉矶市中心 （Downtown LA） 。 登上公交车的那一刻，另一个世界便已拉开序幕。车 ...

这应该是我第几十次踏上美国的土地了吧，单是过去这一年，便已是第四次。过往的记忆，美国在我心中是非常好的印象，"灯塔国"的代名词， 全球创新的引擎，医疗技术的麦加，精英荟萃的殿堂。 看着这些景象，我再深入设想，社会上的有钱人是否应该去救助他们？从人道主义的角度，答案是肯定的。给他们一顿饭，一个遮风避雨的住 处，是守住一个文明社会最后的体面和底线。一个强大的国家，不应该容忍她的公民像这样毫无尊严地活着。 但我的另一个念头又冒了出来。如果福利好到让人可以心安理得地不劳而获，那社会的活力和奋斗精神又从何而来？这种关于"效率"与"公平"的 争论，在美国持续了几十年，让相关的福利政策始终在慷慨与严苛之间摇摆，始终找不到那个完美的平衡点。而这种长期失衡的代价，就赤裸裸 地展现在眼前这座城市的巨大裂痕里：一边是璀璨夺目的金融区，另一边就是这片被阳光遗忘的贫民窟。 上次和耶鲁的教授交流，他说美国活得最惨的中产阶层，既没有富有到可以靠自己花钱搞定衣食住行和子女教育，也没有穷到可以躺在社保体系 上生活，一年到头扣完税，比不干活的人还穷。 之所以有这么好的印象，想必是因为以往的行程，几乎都是被精心安排好的。我和同事们在顶级医院观摩学 ...

调查数据描绘出一幅令人沮丧的社会图景：近70%的美国人不再相信通过努力工作就能实现美国梦，这 一比例达到近15年来的峰值。这种普遍存在的焦虑情绪几乎渗透到社会的每个角落，无论受访者的年 龄、性别、教育程度或收入水平如何。值得注意的是，年收入超过10万美元的家庭中，仍有65%对经济 前景持负面看法。 政治立场与经济感受之间的关联同样引人注目。调查通过六个维度综合评估发现，55%的共和党支持者 对经济感到悲观，而民主党支持者的这一比例高达90%。斯坦福大学经济学教授尼尔·马奥尼对此表示 忧虑：这确实令人沮丧。美国作为超级大国的核心优势之一，就是国民那种'不懈的乐观'精神。正是这 种精神，在过去数十年里推动着创业浪潮和技术创新。 8月28日，美国加利福尼亚州阿罕布拉市一处独栋住宅前，一块褪色的待售标牌在烈日下显得格外醒 目。这栋标价85万美元的三居室房屋已在市场上挂牌超过90天，却鲜有买家问津。这一幕生动反映了当 前美国房地产市场的持续疲软，也折射出更深层次的经济困境。 《华尔街日报》与NORC研究机构联合开展的最新民调揭示了一个令人不安的社会现实：美国民众对经 济前景的悲观情绪正达到历史高点。这项覆盖全美2000 ...
