Yeah no country has ever built a high speed passenger rail network interconnecting cities spread throughout an area comparable to the usa. And it's absurd to think that it could be done in under 20 years and receive massive popular support and have universally recognised benefits. Guys the cost is too high for the biggest economy on earth and the distance is so far that they could never build a railway across it especially not more than 100 years ago.

(Well to be fair the Chinese did also build the railways across the US so maybe they do have something America doesn't)
