Is it morally good to give money to the homeless, why or why not?
gpt
There's a moral and an empirical question here. The empirical question has to do with whether giving money to the homeless really does make their life go better, or makes their life go better than if you had donated that same money to various homeless-helping causes - in short, questions about whether and how giving money to the homeless is really helping them. 

The moral question is whether we're obliged to help those worse off than us. Most philosophers think we are, on the grounds that only caring about ourselves seems like the opposite of moral action. There's a second moral question about *how far* we're obliged to go here: ought we give all our money to those worse off than us, for instance? Famously, Peter Singer has argued that we ought to give almost all (like, all except that which we need to keep living and earning money), although he thinks there are many groups who we ought to donate to before homeless people in Western countries. But plenty of people disagree with Singer for various reasons.
