With F-35, the point has been to bring the generation factor up so that new threats (like newer generation SAMs like S-400, airframes like PAK FA, etc) can be countered. You can't stick with a lower design for a very long time just because it costs less. You have to evolve and improve in the face of changing threat environments. Spending money is a given when defense of the nation is at stake.
You are right about the F-22, though USAF had considered
in the past to sell F-22s to Israel. (just like it was with F-15s, Israel were the first country to get them outside USA).
I am not sure about the F-16, but the FY-15 is surerly better than the F-35.
