Its a simple distinction, dead people (apart from the cost of planting them) don't cost anything so allowing a situation where very poor people have the option to bump themselves off will always be on the table. I see the solution being some form of socialism that ensures that there is a safety net so that people don't end up living in misery and poverty.
It can be abused but done properly, it removes such problems and gives everyone a chance to live like a human being. Simple things like somewhere to live, something to eat and a chance to interact with other people is the model for a viable society, not a money driven, profit system that grinds the face of the poor.
I have seen example here in OZ of people who had nothing and ended up living on the street being provided with housing, albeit small, and they flourish, turn into human beings, develop a lifestyle and become productive. I would rather see this than people living rough in the cold with empty stomachs.
