The veteran population is indeed in general decline - primarily because the vast number of WW II vets are dying-out - skewing the sample. But there are millions of new veterans from the Gulf War period; there will be no shortages (...and there will always be more wars). Furthermore, as the graphs demonstrate, it's no longer just white males. There are growing numbers of Female, Black and other minorities among vets - increasingly reflecting American society in general.
I think the attention we give to veterans one or two days a year is not a "fetish". It's consistant with what others have said above, that these guys are largely ignored most of the time - unless one of them gets up in a tower with a rifle. Often they are depicted as an economic burden. The two main veteran stories in American media right now are the "Return of the Traitor" and the once-a-decade VA scandal.
