HN 读者分享：马斯克并没有“拥有”万亿美元，他拥有的是影响力
2 分•作者: ggm•4 天前
我希望有位有能力的经济学家能写博客指出，马斯克（以及其他超级富豪）并没有像图中所暗示的那样，拥有可以堆积在游艇上的流动现金。
即使是出售他在特斯拉、X 和 SpaceX 的股份这一行为，也会改变这些资产的价值，改变某个国家税收收入，而印钞本身也需要时间和精力，运送现金也会产生费用。
拥有对 1 万亿美元投资的实际影响力是惊人的，但这与“一万亿美元”在性质上并不相同，也并非仅仅是“一百万美元”的量化函数。因为这相当于美国整个经济（约 30 万亿美元）的 1/30，会实质性地改变美国营运资本价值的 3%，以及美国整个股市价值的 1% 多一点。
为了获得这些钱，他会制造一场即时的流动性危机。他会吸走所有的股票交易现金，从而立即贬值所有其他股票。这将是一个巨大的事件。

I wish a competent economist could blog that Musk (and the other uber rich) don't have liquid cash to pile up on their yacht the way the graphics imply.<p>Even the act of selling his stake in tesla and X and spacex would alter the value of the holdings, alter the tax income for some nation state, the act of printing the money would in turn demand time and effort, shipping the money would incur costs.<p>Having the effective influence over investment disposition of $1T is amazing but it isn't actually the same thing qualitatively as "one trillion dollars" nor is it just a quantitative function over "1 million dollars". Because it's 1/30th of the entire US economy (around $30t) and so materially alters 3% of the value of the US working capital, and a little over 1% of the entire US stock market)<p>In order to have the money he'd create an instant liquidity crisis. He'd hoover up all the share trading cash, and so would instantly devalue all the other stocks. It would be a massive event.
