Well having seen first hand how the US generally treat anyone who doesn’t conform to their idealistic view of the world I’m not surprised if the paralympics haven’t got the level of support we would expect. However I think the other thing to understand is that the US government doesn’t directly fund any Olympic athlete, (in either the olympics or paralympics). They get money from the TV rights which is then passed on, but there is no “tax” money issued to athletes. Corporate sponsors and private donors are a big part of the funding over there. BUT that is a catch 22 – inevitably publicity helps raise funds but without funds gaining profile is very hard.
I am surprised though, that given the number of amputee servicemen in recent years, and the strong US support for its armed forces, that there hasn’t been more opportunity there. The US is generally ahead of the UK in terms of prosthetics for injured servicemen and of course they are generally very fit etc.
