This is one of the most sweeping statements I have seen . It is remiss to assume that everything that is expensive is automatically the "best hardware".
It is very difficult to determine the quality of military grade products , but by extension , look at civillian products . Look at some of the "best hardware" products the US actually manufactures . For e.g Cars - last I heard , the Big 3 were all in financial ruins .
I mean , would any average men in the street American want to buy a Ford or a GM ? Go figure this one.
What I am try to say here is the cost of manufacturing and showmanship in the US and Japan is top notch. Look at how much it cost to purchase a type 90 tank or the FSX-F2. Of course both are build with ultra high quality and cost lot more then the Chinese counterpart but it is twice as good? PLAN have a different philosophy, I think it have to do with cost/performance ratio.
