True, many other government contractor projects have been effective graft vehicles. The F-35 jet and the SLS rocket are other, very current examples. People have begun to catch on about nuke plants; they started out as a scam to make the uranium economy more favorable for weapons work, and that has been baked in.

Notable recent exceptions include solar and wind farms, partly I expect because people can tell how much they should cost: N panels x $P per panel, N turbines x $P per turbine. Also, people doing them tend to be idealists; they want the most power out that money can buy, anywhere else if not here.
