美国每年有5350万人次卖血。。。

In 2019, the U.S. received 53.5 million paid plasma donations.

The number of plasma donation centers in the U.S. more than doubled between 2014 and 2021.

US supplies about 70% of the world's plasma needs.

In 2023 alone, the US pulled in a staggering $37 billion from blood product exports

卖血是美国目前出口的拳头产品



按这个统计，每年5350人次卖血，那如果小红书上说美国有4000万人靠卖血为生，那这4000万人，平均每人每年卖血1.34次，收入67元，一年要靠这67元维持生计挺难的。
