The easiest way to increase profits is to lower labor costs. There are four ways of doing this. One is to move manufacturing jobs offshore where labor is cheaper. Another is for corporations to claim falsely that there is a shortage of American labor and to get H1-B and L-1 visas approved to bring in cheaper foreign labor to displace American workers. Another is to replace humans with AI and robotics. Another is to move back office operations and consumer service to countries where wages are low. The most visible are the work visa entrants into the United States.
When the corrupt US Congress passed the law that enables US corporations to fire their US work force and replace it with imported non-American labor, a few members who still represented Americans instead of corporations put into the law that the visa programs depended on corporations being unable to find American workers.
There were unlimited amounts of American workers available , including those abandoned by US corporations who took their production for US markets offshore to lower paid foreign labor. But American law firms rushed to hide the availability of American workers. For example, the law firm Cohen & Grigsby used a marketing video to demonstrate how the firm could enable clients to evade the restrictions on replacing their American workers with imported foreigners on work visas. Hire us, said the law firm’s marketing manager, and we promise “not to find a qualified and interested US worker.”
