For any city to prosper, the accessibility needs to be the first requirement. It seems the gov is prioritizing this aspect. With more flights (especially international), airport expansion, and trains. This potentially drives more local/foreign businesses and investors.
Just my very prelim view. I feel Manila is turning into a Gong show. Its like building on top of garbage. While Clark looks like its building more from scratch. Ive been to manila countless times, but never been to clark. So I will reevaluate my POV once I get a chance to explore clark.
