Indeed, the Philippines is awash with under utilised degree qualified talent. When the Americans pulled out of the Phils, principally from Clark Airbase, and Subic Bay; Bataan and Zambales had the dubious privilege of having some of the most qualified tricycle and jeepney drivers in the Philippines. Many of them having licences to work on many varieties of aircraft C130's C147's etc; and never found such work again.
Currently the Philippines continues to churn out graduates at an alarming rate, many of whom have very little chance of finding any employment, and do not have the experience to secure appropriate overseas work..
Hence the tendency to find teachers working as domestics; nurses are working as care assistants in retirement homes, engineers working as builders. The one thing they have in common is that they are all punching below their weight in terms of salary, and most are exploited by their employers..
