Why did the New Republic have such a small fleet?

[Dark Primus]

Compare to the Empire the NR fleet is small and insignificant, but compare to the OR the NR fleet appears to be bigger and more powerful.
Why didn't they build up a large fleet when NR faced imperial warlords after the other? Or maybe they did but took heavy losses after each warlord?
Is it due to lack of natural resources, long time to train crews to man the starships, lack of economic resources? (I seriously doubt that) or was it due to the NR politicians were incompetent, were not willing to give the military the resources to build up their fleets?


Well now Yuuzhan Vong should be in trouble if NR is using Kuat Drive Yards to 100%, they should be able to replace their ships faster then YV can destroy them.
