The ugliness of US immigration policy is once again evident. There is national outrage that separating children, often infants, from their parents is wrong. There is also national consensus (nine out of ten people in the US) that people brought here by their parents, the Dreamers, should not be forced out of the country as adults. The highly restrictive, dysfunctional immigration system in the United States serves the interests of big business and US Empire. Investors can cross borders to find workers who will accept slave-labor wages and dangerous environments, but workers cannot cross borders to find better wages and safety.
US-pushed corporate trade agreements serve the interests of transnational corporations, allowing them to legally take advantage of cheap labor and to steal natural resources, but workers cannot cross borders when their economy is destroyed or their communities are poisoned.
US militarism and regime change cross borders to replace governments that are working to improve the lives and autonomy of their people and install authoritarian governments, but people who are facing the terrorism of US-supported security states cannot cross the border to find refuge.
The violence of the drug trade that serves US consumers creates mafia and gang violence in other countries, but people who live with the violence of drug gangsterism cannot cross borders to escape.
