English might be benefit but not in all situations.
Actually I’m partially agree with this statement (With English, you'll feel powerful, in control of your life and happy. People will admire and respect you.) Because not all countries admire people who speak English as a second language. In some countries people admire there own language. Atypical example for this situation is France where French people are very proud to their language. Moreover, people who think that English is very important for jobs, not all jobs require English language qualification; we can see many people can be happy and powerful while they speak only one language. We can’t over generalized this issue although it could bring a significant benefits and secure people future.
