One way to get better at infrastructure is to actually build it. Japan also massively over-payed for their first High speed rail, but got better at it. If a nation pays a lot for a given infrastructure project because the nation is developing the means to produce it, then that nation would likely be able to produce the thing better later. Maybe that's Japan. If a nation pays a lot for a given infrastructure project because corrupt interests have positioned themselves to soak up a lion's share of the money, there's no reason to think that won't happen the next time. That's what happens in the US. Further, thing about the US is that failed public transit project have become normal and accepted. Something is needed to change this but uncritically throwing money at them obviously won't be it.
