根据皮尤研究中心的数据显示，2025年美国中产阶级的比例已降至50%以下，这是首次出现这种情况。 过去的美国梦似乎已不再，努力向上爬的梦想变得遥不可及。2025年，街头流浪者的数量比去年增加了 18%，其中25岁以下的年轻人占了27%，更令人痛心的是，流浪儿童人数达到14.8万，比去年增加了 33%。 2025年，38岁的程序员杰克·威尔逊坐在西雅图的天桥下，啃着冷三明治。六个月前，他还在亚马逊工 作，年薪45万美元，住着月租3500美元的公寓。如今，他只剩下一个背包，里面装着胃药和失业证明。 这个故事并非电影情节，而是美国2025年生存红线下的现实。越来越多的人正在被推向贫困的边缘。美 国官方规定的贫困线是四口之家年收入3.215万美元，但在西雅图这样的大城市，真正的活命线却需要 13.65万美元，这个数字来自美联储2025年的报告。 住房成本是主要原因。西雅图一套80平米的房子，每月需要4000美元的月供，加上医保、孩子学费和食 品杂货，一家四口每月的固定支出超过1.1万美元。更令人担忧的是，活命线还在不断上涨。从2019年 到2025年，美国家庭的月支出上涨了42%，但工资只上涨了7.3%。 但除了高成 ...

Economic Performance - In the first quarter of 2025, the US economy contracted by 0.5% on a year-over-year basis, which was below expectations and undermined confidence in sustained economic growth [1][3] - The contraction is attributed to complex structural issues within the economy, with tariff policies significantly impacting both imports and exports [1][5] Trade Dynamics - The US saw an import growth adjustment to 37.9% and export growth adjusted to 0.4%, with net imports dragging down GDP by nearly 4.7 percentage points [3] - The reliance on imports has increased, exacerbating the trade deficit and highlighting the imbalance in the economic structure [3][6] Consumer Spending - Personal consumption expenditure, which accounts for about 70% of GDP, contributed only approximately 0.3 percentage points to GDP growth in the first quarter, indicating a decline in consumer purchasing power [3][5] - Consumer confidence has weakened, particularly in an uncertain economic environment, which has become a significant factor in hindering economic growth [3][8] Tariff Policy Impact - The "America First" trade policy implemented by the Trump administration aimed to protect domestic manufacturing but resulted in increased prices for imported goods, raising production costs for US businesses [5][6] - This policy has inadvertently shifted the burden onto consumers, leading to a slowdown in overall economic growth [5][8] Global Economic Uncertainty - The interconnectedness of the US economy with global markets means that uncertainties in other major economies, such as China and the EU, directly affect US export growth [6][8] - The slowdown in global economic growth has led many US companies to reduce investment and production plans, further contributing to domestic economic contraction [6][8] Structural Issues - The current economic challenges reflect long-term structural problems, with the US economy's dependence on external markets making it vulnerable to global uncertainties [8] - Addressing these structural issues, including reducing reliance on imports and adjusting trade strategies, is crucial for sustainable economic growth in the future [8]
