Why did American companies send so much of their business to other countries?

American companies have outsourced a significant portion of their business to other countries primarily to reduce labor costs and increase profit margins. By relocating manufacturing and services to countries with lower wages, companies can save on operational expenses. Additionally, globalization has enabled access to larger markets and diverse talent pools, further driving the trend. Lastly, advancements in technology and communication have made it easier to manage operations across borders.
