English can find more job opportunities
Many large companies around the world require that their employees speak English. In some cases, these companies are requiring their workers to only use English.
As the world becomes more global (better connected), it is only natural that big businesses will want and need to communicate more. Right now, everyone is trying to learn and communicate with English. English is becoming the common language that people from different countries and cultures can use to communicate with one another.
For example, imagine that a businessperson from Israel, who speaks English and Hebrew, wants to do business with a someone from South Africa, who speaks English and Afrikaans. Even though they both started learning English as a second language in elementary school, they can use English to communicate with each other!
