That's not fair to the toddlers; their crap tends to be safely contained in a diaper as opposed to their heads.

It's not totally clear that the gigantic push to run rail lines through undeveloped parts of North America "ahead of demand" for reasons of genocide (aka "white settlement"), especially the transcontinental routes, was the smartest investment, even leaving aside the horrific crime it represents. We probably would have gotten greater ROI connecting more developed places on a piecemeal basis and extending the rail network more slowly in the West (and probably even more rapidly in the developed East) instead of founding new towns along brand-new rail lines. There is a reason the federal government was so involved in the finance of these things: left alone, private Eastern capital would not have done things the way they were done, which was chiefly to "open the frontier" aka accelerate the genocide.

I certainly think it was a mistake.
