What kind of multiple contraction effect will the closure of USAID bring? Whether Trump realizes it or not, the closure of USAID will send a strong signal of overseas contraction to domestic private contractors and overseas service support providers in the United States. Although many of these expenses are incurred overseas, they are actually earned by American companies, some direct government procurement, and some orders brought by exerting influence abroad, such as bribing local officials and exerting ideological pressure to squeeze Huawei out of the communications field and turn to their procurement, etc.
