Years ago, illegal immigrants came to America for opportunity, and today, some still do. But increasingly, illegal immigrants are coming for welfare, and many have no interest in learning English or assimilating. A country's immigration rules should be based on the needs of the country. America does not need millions of unskilled, poorly educated, non-English speaking immigrants who have no desire to work or assimilate. Our classrooms are overcrowded. Many hospitals in the southwest have closed because by law they had to treat anyone who needs emergency care. Illegals have used our ER's as doctors' offices, and almost none of them pay their hospital bills. The information that has consistently gone unreported is the many hidden costs of illegal immigrants. Our news media for decades have promoted sad stories of noble, worthy immigrants. But we see the Mexican gangs that have taken over our high schools. The high number of incarcerated illegals in southwestern states, etc. etc. etc.
