IMHO its not just poverty. Culture is also a factor in this mindset. If we look at our history, we always had an odd bias to foreigners especially Caucasians to the point of treating them as superior to us. From the first Spanish conquistadors to the Americans liberators, our history showed our affinity with foreigners. Among Asian countries, it seemed that only our nation is the least nationalistic and has no concrete identity. We marvel at foreigners and look down on our own. We prefer Fil-Foreign mestizos/mestizas talents more than our local ones. We idolize the Jasmine Triases etc. and gave them treatments normally reserved for dignitaries yet media provides only tidbits of our locally raised pinoy's exploits abroad.
I think the Filipino nation needs an overhaul in nationalism and education.
