Global corporations are different than monopoly corporations. Their structure, policies and actions are different. These new global giants have developed new strategies to fit this new structure. One is the spinning off of subsidiaries to create the appearance of different ownership to make it difficult to determine who really owns, controls and runs the corporation. The result is that U.S. mills are being closed and thousands of workers laid off.
Unemployment is now at a crisis level in steel.
There are all kinds of solutions being proposed, from both sides of the class divide. The solution that seems to be getting the most support so far is the proposal to introduce a new law that would make it illegal to import foreign steel. One problem with this is that it would provoke and legitimize a retaliation boycott of U.S. products by the world markets. A law against foreign imports would help the steel workers somewhat. But it would be at the expense of the steel workers in other countries.
