Why cant our airport be as beautiful and modern as others?

if anyone of you who spend most of his life basically in a suitcase then you would realise something is amiss with our BIA. whilst most airports have either had major facelifts or new ones built or replaced, ours somehow has remained an "antique" worth to be classified as part of the national heritage or should I say a historical artifact.  common civil aviation people! wakeup! look at Miri, Kuching and KK..we dont have to go far away to see that other countries have moved and we have remained static. is this really a country of unexpected treasures when the airport with its pathetic facilities, faulty aircon and aerobridges only seen in the third world can make tourist feel welcome? I think NOT.
