F-22 cost

The price quotes on the F-35 are ranging between 50 million and 100 million with loads of uncertainty. Very understandable as this is a very new plane, not even fully developed.

The eurocanards seem to cost all between 50 and 80 million.

The F-22 is costing according to public sources, around 170 million a piece. For F-22, all parameters to determine the price are fully known as it is in full production.

So what is really justifying that the F-22 sooo expensive??

Is the taxpayer paying for exclusivity [like buying a Ferrari] and has the price nothing to do with production cost + a reasonable profit?

Or are there real world technical explanations for this price tag? if so, what are these?
