I was having a political discussion with roots in philosophy, where I was explaining an idea for a government program which would enforce equal opportunities for children who have poor / parentally uninvolved home environments, and I ran into a philisophical obstacle: The other person responded with "Not my my tax money. I don't have kids, don't plan to, and honestly don't care about helping those kids who I don't know."
I thought this might be a dismissible point of view, surely there aren't many with such views - but I then had the same discussion with another person and recieved a similar response: "I know it sounds bad, but honestly I care about helping people I care about and that's it."
So, I grew up in a religious family and the only supportive reasoning I've been exposed to is religiously rooted. "God says so." - In society, one can't support arguments with religion - And I personally don't subscribe to this form of reasoning either. But I do feel inclined to argue in support of helping others.
How can one argue in support of helping others without citing religious dogma as supportive reasoning? How can I counter a "selfish" argument without religion?
