马克·库班在周四卡玛拉·哈里斯的威斯康星州集会上接过麦克风，猛烈抨击了 fellow billionaire 唐纳德·特朗普的经济政策。这位“鲨鱼坦克”明星嘲笑了这位前总统提出的提高关税的提议，特朗普曾表示，对所有进入美国的商品征收 10% 或 20% 的关税，并补充说这将相当于“对所有人的税收”。库班说，他认为特朗普，至少在 90 年代和 2000 年代初，“过去知道关税是如何运作的”，但那些日子早已过去。库班还批评了特朗普提出的对来自中国的进口商品征收 60% 关税的提议，达拉斯小牛队的这位前主要所有者表示，这不是一个好主意。库班解释说，美国人没有意识到他们有多少日常用品是在中国制造的，如果对中国进口商品征收关税，这些商品的价格到明年圣诞节可能会上涨 50% 或更多。他补充说，当地企业主也可能感受到关税带来的痛苦，甚至被迫关门歇业。特朗普竞选团队没有立即回应《财富》杂志的置评请求。经济学家表示，特朗普的关税提议将增加中产阶级家庭的成本。根据彼得森国际经济研究所 8 月份的一项研究，如果实施这些关税，平均美国家庭每年可能要多支出 2600 多美元。特朗普此前曾错误地描述了关税的运作方式，称之为“对其他国家的税收”。实际上，关税是由购买进口产品的美国消费者支付的。右倾的税收基金会高级经济学家埃里卡·约克写道，10% 的关税（如特朗普提议的那样）的成本每年可能达到 3000 亿美元。特朗普表示，他认为关税是筹集资金的一种方式，以便政府可以降低税收，他的前任首席贸易官员罗伯特·莱特希泽表示，关税应该旨在消除美国贸易逆差。然而，特朗普的经济计划有可能重塑全球贸易，对其他国家提高关税可能会导致它们对美国制造的商品征收或提高关税。对于库班来说，这种背离自由贸易政策的举动是错误的一步。

Mark Cuban took the mic at Kamala Harris’ rally in Wisconsin on Thursday to bash fellow billionaire Donald Trump’s economic policies, and he didn’t hold back.The Shark Tank star mocked the former president’s proposal to raise tariffs, which Trump has said could reach 10% or 20% for all products coming into the U.S., and added that it would amount to “a tax on everybody.”Cuban said he believes Trump, at least in the ‘90s and early 2000s, “used to know how tariffs work,” but those days are long gone. “I don’t know what happened to him,” Cuban said.Cuban also criticized Trump’s proposal to enact a 60% tariff on imports from China, which the former principal owner of the Dallas Mavericks said was not a good idea.“This man has so little understanding of tariffs he thinks that China pays for them,” Cuban said. “This is the same guy who also thought that Mexico would pay for the wall.”Cuban explained that Americans don’t realize how many of their everyday products are made in China, and with a proposed tariff on Chinese imports, the price of those products could skyrocket by 50% or more by Christmas time next year. He added that local business owners could also feel the pain of tariffs, and even be forced to close up shop.The Trump campaign did not immediately respond to Fortune‘s request for comment. Economists have said Trump’s tariff proposals would raise costs for middle-class families. The tariffs, if implemented, could cost the average American household more than $2,600 a year, according to an August study by the Peterson Institute for International Economics. Trump has previously mischaracterized how tariffs work, calling them “a tax on other countries.” In reality, tariffs are paid by American consumers buying imported products. The cost of a 10% tariff (as Trump has proposed) could reach $300 billion per year for American consumers, wrote Erica York, a senior economist at the right-leaning Tax Foundation.Trump has said he sees tariffs as a way to raise money so the government can lower taxes, and his former top trade official, Robert Lighthizer, has said tariffs should be aimed at eliminating the U.S. trade deficit. Yet, Trump’s economic plans have the potential to reshape global trade, and hiking tariffs on other countries could lead them to enact or increase tariffs on U.S.-made goods. For Cuban, this move away from free trade policies is a step in the wrong direction. “The way [Trump has] been thinking about tariffs and trade now, something’s a little bit lost,” he said. “And now his trade policies, particularly with tariffs, are basically just gibberish.”
