You may have heard the term “the American Dream”. In 1848, James W. Marshall found gold in California and people began having golden dreams. That 19th century “American Dream” caused the Gold Rush and gave California its nickname(绰号) of the “Golden State”.
The American Dream drove not only 1800s gold-rush prospectors (淘金者) but also waves of immigrants throughout that century and the next. People from Europe, and a large number of Chinese, arrived in the US in the 19th century hoping that in America they would find gold in the streets. But most, instead, worked as railroad labourers. They created the oldest Chinatown, in San Francisco, and gave the city a Chinese name “the old gold hill”.
In the 20th century, some critics (评论家) said that it was no longer possible to become rich through determination and hard work. Unfair education for students from poor families and racial discrimination (歧视) almost made the American Dream a nightmare (噩梦).
Then, in the 1990s, California saw a new wave of dreamers in Silicon Valley. People poured their energy into the Internet. This new chapter of the American Dream attracted many business people and young talents from China and India to form start-ups and seek fortunes in America.
Better pay, a nice house, and a rising standard of living will always be attractive. However, the new American Dream is no longer just about money. It encourages Americans to use money with a plan, protect the environment, raise the quality of life, and promote social justice.
The Governor of California, Arnold Schwarzenegger, has become the model of the new American Dream. After years of hard work, he grew from a poor young man from Austria into a movie superstar and then governor. Many people hope his story can save the American Dream and give California a brighter future.
