第二大利好，是能戳破美元GDP计价的水分。中国GDP的含金量，也能更真实地展现了。按照中美预 测，美国2025年GDP，可能会突破30万亿美元。我们自己，则是140万亿人民币。用人民币来计算，那 不用说，这个GDP规模再创新高了。可是如果换算成美元计价呢？大概20万亿美元规模，只相当于美国 GDP的67%。要知道2021年，中国GDP总量，达到了美国的77%。难道说？咱们辛苦干了四年，还倒退 了10%吗？中美GDP差距，难道越来越大了？很多人用这种数据，唱衰中国经济。实际情况，当然不是 这么回事。 首先，美元加息带来的潮汐效应，让美元不断升值。对应的，人民币也出现了阶段性贬值。2021年，1 美元兑6.45元人民币。2025年呢？最夸张的时候，1美元能兑7.35元人民币，人民币贬值了超12%。未来 如果人民币稳定升值，中美之间的实际GDP差距，将会越来越小，甚至中方能实现反超。为啥呢？因为 汇率差缩小，能挤出大量金融水分，数据会变得更加真实。 黄奇帆预测，人民币将进入十年升值周期！很多人又会拿出经典语录了，这跟我"月薪三千"有啥关系？ 这回还真就有关系，而且关系很大。咱做个假设，人民币升值了一倍，你的"月薪三 ...
