It’s because you opened with “Accepting an onsite job […] places the responsibility on you to be able to commute there”, as if people are choosing this when there are other options. This “responsibility” is foisted onto people by management that demands it, and a society that demands most people labor or die. Saying “you accepted this under duress, now accept the consequences” is crap.

The rest of your point about reliable transportation and fair wages is fine.
