"Probably" see better results? I don't have, nor will I fetch for, the number of people who are solely reliant on SS, but my father is one of them. And he said the exact same words as you to me when I was a sprout. Now, after some bad decisions, and health issues as a direct result of long arduous work, he is glad to have that net.
Please, don't tell me about my duties as a son, I've supported two family members through cancer, simultaneously. If/when it comes to it, he will be taken care of by me & siblings. How about the millions? who don't have children able to care for them? The streets is it? More welfare? I'd love to hear about a more sustainable option that doesn't include 'probably'.
