What makes someone a loser in your eyes?

I have spent the last four years "putting myself out there" i.e. speaking to anyone who will speak with me. I am a bit polarizing, some fun loving people love to talk to me, but besides that it's mostly desperate, needy people who are lonely for a good reason. I spent thousands of dollars and hours, bore as much emotional weight as i could for them, and gave them the best advice i could muster. It seems people like this simply don't have what it takes to help themselves no matter how much assistance is provided. I've met personally thousands of these people. And I have lost respect for all people. I see some of my coworkers slaving themselves away for a little extra cash to help their families, or greedy rich ceo's, money hungry hustlers like my brother..... i have lost all respect for all people. I had such hope for this world but, people are pathetic and disgusting to me now, even myself. i have trouble imagining a motivation someone could have that i would admire. What is this? does this have a name? does this have a cure?
