There are always two sides of the coin. Two sides of the moon, the light and dark. In nationalism too, there are good and bad effects. I will write about the good ones first. The negative ones will be in the next few days or weeks.
1. It could develop our own national identity. No longer pretensions. No more wearing the masks of Spain or America.
2. It will be good for the local economy. When a Filipino loves the Philippines, he thinks what’s good for the Philippines. He may just remain in the Philippines to help out other Filipinos or go to the other countries to wok, but the Philippines still in his mind and heart.
3. National unity. It may not be perfect, but overall there will be unity. Even the rich countries still has some kinks to iron out.
4. Less regionalism. When there is unity, other regions would think wholly. Lesser discrimination on other ethnicities.
