I think we should erect a statue of liberty at the Tijuana border. This would represent the principle of allowing people of other countries to emigrate here as exists on the east coast. It is obvious that Mexicans come here to work, that they are needed. They are doing work that most US citizens won't do. Why aren't they welcomed?
A related concept is how white people have traditionally suppressed people of color: indians, chinese, blacks
Europeans were welcomed on the east coast by the statue of liberty.
This statue would have to built of steel so it couldn't be burned down, on land owned by a sympathizer, of a size that is practical to build.....depending what kind of money could be raised.
