I want to give them money but since my childhood my parents pretty much told me that they are all either faking it or are too lazy to go to work for money. I mean, I guess they can go to work but not everyone gets accepted to work as easy as it sounds like.
I like Kant’s take on this. He argued (roughly, by memory) that giving to people begging on the street directly was a selfish act, as it’s satisfying our own need to feel better about ourselves more than the needs of the homeless population, and would lead to an unfair distribution giving more money to those who are talented at evoking empathy rather than those that might need it the most. He argued that the unselfish thing to do would be to donate to the cause indirectly, responding not to the emotional response in the moment but to a rational consideration of the needs of the homeless population.
I think he has a point. That said, there’s nothing wrong with being selfish every now and then, especially not if your selfishness gives someone a warm meal. And empathy is a healthy human reaction.
Your parents seem to have failed to grasp the challenges facing the homeless population. A better take would be “don’t give that guy money, start donating regularly to a local charity instead and help make sure that help is given to all those who need it”.
Oh, and also, rally for political change.
