Should they take a 60% pay cut to do back-breaking labor at a construction site? Take a bigger pay cut to wash dishes at a restaurant? Or perhaps they could work long hours subsistence farming; that's a pretty common option in Pakistan, if the numbers I'm seeing are at all accurate. I know people who used to do this, and from what I hear it kind of sucks.
Taking distasteful options away from poor people because they might choose those options is one of my least-favorite forms of moral grandstanding, because it hurts people who already have it rough.
