Body shop
WItCH companies are core for US success
They are these huge companies that I think are all or mostly headquartered in India. They are heavily leveraged by FAANG companies and other large corporations to supply cheap labor. From personal experience I can say they are doing a great job at displacing permanent U.S. residents and driving down the wages of many tech roles. These companies are parasites.
