Thoughts: Why do some Filipino parents choose to teach their kids English only?

Genuine question lang. Ano kaya ang thought process ng mga local Pinoy parents na English lang ang itinuturo sa mga anak nila? I understand wanting your kids to be fluent in English, especially since it’s useful for school and work, pero bakit hindi both languages?

Parang mas okay naman sana if they can speak English and Filipino fluently. Curious lang ako sa perspective ng mga parents who choose to raise their kids speaking English only. 😭
