This is an interesting statistics to bring up because in the Philippines ( unlike in many other countries) English is the medium of instruction and does measure the level of education. You will also be surprised at how badly many people there speak their own language. What people speak on the streets is an atrocious mixture of Tagalog and English and it is tolerated in society that prides itself on tolerance. Every time I try and make a somewhat normal sentence in Tagalog people just go ooh and ahhh and say: "Oh my God, your Tagalog is so deep, you speak it better than me, wow!" For example you say simple sentences like:Occasionally, I will interview a highly educated Filipino for the IELTS test (Between 8-9 band score), but this seems to be increasingly getting rarer as most seem to be leaving the country to immigrate to Canada, Australia or New Zealand. I interview thousands of Filipinos a year and they are supposed to generally be the higher educated of the mass population, and to be honest there aren't that many left in the Philippines. The ones with means have already left or are in the process of leaving the country permanently. Most Filipinos I interview fal between the 5-7 band range, more so the lower half.
"Where is the company headquarters? The humidity today is really high! This can cause damage to your lungs". With every word being in Tagalog.
Then it is like- "oh, wow, a poet, a bookworm! a smart ass", etc.
As the US, the Philippines has been dumbing down. It used to be quite a progressive Asian country with a very large intellectual class but no more. Those have mostly emigrated. There is not much patriotism in the Philippines and an average person does not mind leaving as long as it is for a good job.
