[Kulturkampf]

Some ethnic groups are still outsiders.

Mexicans and blacks endured some hardships 30-40 years ago but still have not recovered from them and have abnormally high instances of criminality, drug use, etc. compared to other groups. The idea that immigrant groups automatically get better is poppycock.

The Jews and the Chinese were in identical situations to the Hispanics 70 years ago and now they are moving along very far into our societies while hispanics are not.

Immigration does not automatically mean that people are going to be 'on top in 30 years,' only certain groups succeed in assimilation.
