alt Hacker NewsInfrastructure Week was literally a running joke throughout Trump's first term because his staff would start by hyping up some substantive policy changes they wanted to pass, only for it to be completely derailed by yet another ridiculous/stupid/corrupt/insane thing Trump or one of his top people did.
Clearly Trump himself has no interest in these sorts of substantive projects, I mean just look at his second term. He has even less interest in policy this time around and isn't even pretending to push for infrastructure or similar legislation.
My point is he made these claims on the campaign trail, which I cited; he had a real domain expert on his team, which I cited; and it became evident even a year in that his administration wouldn't deliver on that plan according to his own domain expert.
That's a fairly standard case of an ineffective politician casually jettisoning campaign promises once he's in office. And he jettisoned them because he couldn't sell the Republicans on a trillion dollar infrastructure package.
