The F-35 is cheap for what it is capable of. F-22 and F-47 are immaterial. And the export F-35 is nerfed to some extent.
The unfortunate reality, which the US is exploiting, is that Europe would struggle to produce an equivalent of the nerfed F-35, never mind one that hadn’t been nerfed. As a consequence, the US can sell nerfed F-35s all day. There aren’t many alternatives currently. 4.5 gen aircraft aren’t competitive in a serious conflict and everyone knows it. Even the US has to contend with that reality.
