I think I'm comfortable arguing that it is much more ethical to do voluntary human testing, as humans will always have more options than animals in cages - unless we are talking something like human trafficking, but I don't think that's what you are bringing up.
As for your example, I too knew someone living a pretty terrible life doing trials for a living, that died sadly. While I understand your point, I'm sure you can think of many avenues for this person to make a living without doing trials - i.e. stocking shelves, working a warehouse, janitorial work, service, etc. If they are under precarious circumstences, there are many options still.
