Interesting analogy, although with El Norte, they were leaving their home for good, and going to a better place. In Last Train Home, their's is more like a work commute, and the place they are commuting to is pretty miserable. Nonetheless, interesting analogy, both films are fantastic. More than anything, I marvel at how monastic the lifestyle of the Chinese couple is. They do their work, they eat, they sleep, and then they do it all over again. And they never seem to complain. It's impressive.
