Yes, mjr accurately describes the situation this year, with a few extra expensive trips and a shortfall in the travel budget. Longterm, I don't see a lot of entities (besides nike) interested in sponsoring T&F in the U.S. It's not exactly NASCAR, NFL or March Madness. I'd guess in a few years USATF, if there still is such a thing, will send potential medalists only to most events, as opposed to full teams, as some countries do now.
As long as there's an NCAA, the U.S. will still dominate the 100m-400m, but when the bottom falls out of longterm post-collegiate development funding and travel opportunities, I would expect not many athletes in the technical and endurance events will be willing/able to hang in there until age 30. In 10 years, the U.S. may still be the number one nation in T&F off sprint points, but the age of great powers (USSR, DDR, USA) has ended and the points will be spread through more nations, most from the developing countries, unless China fills the vaccuum and becomes dominant. The potential is there for China to build a team no one could match.
